 ## Installation
 
 First, download the repo to a location your SAS system can access. Then update your sasautos path to include the components you wish to have available, eg:
 
 ```sas
-options insert=(sasautos="/your/path/macrocore/base");
-options insert=(sasautos="/your/path/macrocore/meta");
+%let repoloc=/your/path/core;
+options insert=(sasautos="&repoloc/base");
+options insert=(sasautos="&repoloc/ddl");
+options insert=(sasautos="&repoloc/fcmp");
+options insert=(sasautos="&repoloc/lua");
+options insert=(sasautos="&repoloc/meta");
+options insert=(sasautos="&repoloc/metax");
+options insert=(sasautos="&repoloc/server");
+options insert=(sasautos="&repoloc/viya");
+options insert=(sasautos="&repoloc/xplatform");
 ```
 
 The above can be done directly in your sas program, via an autoexec, or an initialisation program.

 - Avoid naming collisions! All macro variables should be local scope. Use system generated work tables where possible - eg `data ; set sashelp.class; run; data &output; set &syslast; run;`
+- Where global macro variables are absolutely necessary, they should make use of `&sasjs_prefix` - see mp_init.sas
 - The use of `quit;` for `proc sql` is optional unless you are looking to benefit from the timing statistics.
+- Use [sasjs lint](https://github.com/sasjs/lint)!
 
 ## General Notes
 
 - All macros should be compatible with SAS versions from support level B and above (so currently 9.2 and later). If an earlier version is not supported, then the macro should say as such in the header documentation, and exit gracefully (eg `%if %sysevalf(&sysver<9.3) %then %return`).
 
+## Breaking Changes
+
+We are currently on major release v4.  Breaking changes should be marked with the [deprecated](https://www.doxygen.nl/manual/commands.html#cmddeprecated) doxygen tag.  The following changes are planned when the next major/breaking release (v5) becomes necessary:
+
+* mf_getuniquelibref.sas to have the deprecated maxtried parameter removed (no longer needed)
+* mp_testservice.sas to be renamed as mp_execute.sas (as it doesn't actually test anything)
+* `insert_cmplib` option of mcf_xxx macros will be deprecated (the option is now checked automatically with value inserted only if needed)
+* mcf_xxx macros to have `wrap=` option defaulted to YES for convenience.  Set this option explicitly to avoid issues.
+* mp_getddl.sas to be renamed to mp_ds2ddl.sas (consistent with other ds2xxx macros).  A wrapper macro is already in place, and you are able to use this immediately.  The default for SHOWLOG will also be YES instead of NO.
+* mp_coretable.sas will be replaced by the standalone macros in the `ddl` folder (which are already available)

+  @brief Returns E8601DT26.6 if compatible else DATETIME19.3
+  @details From our experience in [Data Controller for SAS]
+  (https://datacontroller.io) deployments, the E8601DT26.6 datetime format has
+  the widest support when it comes to pass-through SQL queries.
+
+  However, it is not supported in WPS or early versions of SAS 9 (M3 and below)
+  when used as a datetime literal, eg:
+
+      data _null_;
+        demo="%sysfunc(datetime(),E8601DT26.6)"dt;
+        demo=;
+      run;
+
+  This macro will therefore return DATEITME19.3 as an alternative format
+  based on the runtime environment so that it can be used in such cases, eg:
+
+      data _null_;
+        demo="%sysfunc(datetime(),%mf_fmtdttm())"dt;

+/**
+  @file
+  @brief Used to capture scope leakage of macro variables
+  @details
+
+  A common 'difficult to detect' bug in macros is where a nested macro
+  over-writes variables in a higher level macro.
+
+  This assertion takes a snapshot of the macro variables before and after
+  a macro invocation.  Differences are captured in the `&outds` table. This
+  makes it easy to detect whether any macro variables were modified or
+  changed.
+
+  The following variables are NOT tested (as they are known, global variables
+  used in SASjs):
+
+  @li &sasjs_prefix._FUNCTIONS
+
+  Global variables are initialised in mp_init.sas - which will also trigger
+  "strict mode" in your SAS session.  Whilst this is a default in SASjs
+  produced apps, if you prefer not to use this mode, simply instantiate the
+  following variable to prevent the macro from running:  `SASJS_PREFIX`
+
+  Example usage:
+
+      %mp_assertscope(SNAPSHOT)
+
+      %let oops=I did it again;
+
+      %mp_assertscope(COMPARE,
+        desc=Checking macro variables against previous snapshot
+      )
+
+  This macro is designed to work alongside `sasjs test` - for more information
+  about this facility, visit [cli.sasjs.io/test](https://cli.sasjs.io/test).
+
+  @param [in] action (SNAPSHOT) The action to take.  Valid values:
+    @li SNAPSHOT - take a copy of the current macro variables
+    @li COMPARE - compare the current macro variables against previous values
+  @param [in] scope= (GLOBAL) The scope of the variables to be checked.  This
+    corresponds to the values in the SCOPE column in `sashelp.vmacro`.
+  @param [in] desc= (Testing scope leakage) The user provided test description
+  @param [in] ignorelist= Provide a list of macro variable names to ignore from
+    the comparison
+  @param [in,out] scopeds= (work.mp_assertscope) The dataset to contain the
+    scope snapshot
+  @param [out] outds= (work.test_results) The output dataset to contain the
+  results.  If it does not exist, it will be created, with the following format:
+  |TEST_DESCRIPTION:$256|TEST_RESULT:$4|TEST_COMMENTS:$256|
+  |---|---|---|

+  Why use mp_ds2csv over, say, proc export?
+
+  1. Ability to retain leading blanks (this is a major one)
+  2. Control the header format
+  3. Simple one-liner
+
+  @param [in] ds The dataset to be exported
+  @param [in] dlm= (COMMA) The delimeter to apply.  For SASJS, will always be
+    COMMA. Supported values:
+    @li COMMA
+    @li SEMICOLON
+  @param [in] headerformat= (LABEL) The format to use for the header section.
+    Valid values:
+    @li LABEL - Use the variable label (or name, if blank)
+    @li NAME - Use the variable name
+    @li SASJS - Used to create sasjs-formatted input CSVs, eg for use in
+      mp_testservice.sas.  This format will supply an input statement in the
+      first row, making ingestion by datastep a breeze.  Special misisng values
+      will be prefixed with a period (eg `.A`) to enable ingestion on both SAS 9
+      and Viya.  Dates / Datetimes etc are identified by the format type (lookup
+      with mcf_getfmttype.sas) and converted to human readable formats (not
+      numbers).
+  @param [out] outfile= The output filename - should be quoted.
+  @param [out] outref= (0) The output fileref (takes precedence if provided)
+  @param [in] outencoding= (0) The (quoted) output encoding to use, eg `"UTF-8"`
+  @param [in] termstr= (CRLF) The line seperator to use.  For SASJS, will
+    always be CRLF.  Valid values:
+    @li CRLF
+    @li LF

+/**

+  @brief Checks & Stores an input filter table and returns the Filter Key
+  @details Used to generate a FILTER_RK from an input query dataset.  This
+  process requires several permanent tables (names are configurable).  The
+  benefit of storing query values at backend is to enable stored 'views' of
+  filtered tables at frontend (ie, when building [SAS-Powered Apps](
+  https://sasapps.io)).  This macro is also used in [Data Controller for SAS](
+  https://datacontroller.io).
+
+  A more recent feature of this macro is the ability to support filter queries
+  on Format Catalogs.  This is achieved by adding a `-FC` suffix to the `libds`
+  parameter - where the "ds" in this case is the catalog name.
+
+
+  @param [in] libds= The target dataset to be filtered (lib should be assigned).
+    If filtering a format catalog, add the following suffix:  `-FC`.
+  @param [in] queryds= (WORK.FILTERQUERY) The temporary input query dataset to
+    be validated.  Has the following format:
+|GROUP_LOGIC:$3|SUBGROUP_LOGIC:$3|SUBGROUP_ID:8.|VARIABLE_NM:$32|OPERATOR_NM:$10|RAW_VALUE:$32767|
+|---|---|---|---|---|---|
+|AND|AND|1|SOME_BESTNUM|>|1|
+|AND|AND|1|SOME_TIME|=|77333|
+  @param [in] filter_summary= (PERM.FILTER_SUMMARY) Permanent table containing
+    summary filter values.  The definition is available by running
+    mp_coretable.sas as follows:  `mp_coretable(FILTER_SUMMARY)`. Example
+    values:

   @brief Scans a dataset to find the max length of the variable values
   @details
   This macro will scan a base dataset and produce an output dataset with two
   columns:
 
   - NAME    Name of the base dataset column
-  - MAXLEN Maximum length of the data contained therein.
+  - MAXLEN  Maximum length of the data contained therein.
 
-  Character fields may be allocated very large widths (eg 32000) of which the
-  maximum  value is likely to be much narrower.  This macro was designed to
-  enable a HTML table to be appropriately sized however this could be used as
-  part of a data audit to ensure we aren't over-sizing our tables in relation to
-  the data therein.
+  Character fields are often allocated very large widths (eg 32000) of which the
+  maximum  value is likely to be much narrower.  Identifying such cases can be
+  helpful in the following scenarios:
+
+  @li Enabling a HTML table to be appropriately sized (`num2char=YES`)
+  @li Reducing the size of a dataset to save on storage (mp_ds2squeeze.sas)
+  @li Identifying columns containing nothing but missing values (`MAXLEN=0` in
+    the output table)
+
+  If the entire column is made up of (non-special) missing values then a value
+  of 0 is returned.
 
-  Numeric fields are converted using the relevant format to determine the width.
   Usage:
 
       %mp_getmaxvarlengths(sashelp.class,outds=work.myds)
 
-  @param libds Two part dataset (or view) reference.
-  @param outds= The output dataset to create
+  @param [in] libds Two part dataset (or view) reference.
+  @param [in] num2char= (NO) When set to NO, numeric fields are sized according
+    to the number of bytes used (or set to zero in the case of non-special
+    missings). When YES, the numeric field is converted to character (using the
+    format, if available), and that is sized instead, using `lengthn()`.
+  @param [out] outds= The output dataset to create, eg:
+  |NAME:$8.|MAXLEN:best.|

+  |`Name `|`7 `|
+  |`Sex `|`1 `|

+/**
+  @file
+  @brief Loads a format catalog from a staging dataset
+  @details When loading staged data, it is common to receive only the records
+  that have actually changed.  However, when loading a format catalog, if
+  records are missing they are presumed to be no longer required.
+
+  This macro will augment a staging dataset with other records from the same
+  format, to prevent loss of data - UNLESS the input dataset contains a marker
+  column, specifying that a particular row needs to be deleted (`delete_col=`).
+
+  This macro can also be used to identify which records would be (or were)
+  considered new, modified or deleted (`loadtarget=`) by creating the following
+  tables:
+
+  @li work.outds_add
+  @li work.outds_del
+  @li work.outds_mod
+
+  For example usage, see mp_loadformat.test.sas
+
+  @param [in] libcat The format catalog to be loaded
+  @param [in] libds The staging table to load
+  @param [in] loadtarget= (NO) Set to YES to actually load the target catalog
+  @param [in] delete_col= (_____DELETE__THIS__RECORD_____) The column used to
+    mark a record for deletion.  Values should be "Yes" or "No".
+  @param [out] auditlibds= (0) For change tracking, set to the libds of an audit
+    table as defined in mddl_dc_difftable.sas
+  @param [in] locklibds= (0) For multi-user (parallel) situations, set to the
+    libds of the DC lock table as defined in the mddl_dc_locktable.sas macro.
+  @param [out] outds_add= (0) Set a libds here to see the new records added
+  @param [out] outds_del= (0) Set a libds here to see the records deleted
+  @param [out] outds_mod= (0) Set a libds here to see the modified records
+  @param [in] mdebug= (0) Set to 1 to enable DEBUG messages and preserve outputs

     assigned.
   @param [in] ds= The dataset to lock
   @param [in] ref= A meaningful reference to enable the lock to be traced. Max
     length is 200 characters.
   @param [out] ctl_ds= (0) The control table which controls the actual locking.
-    Should already be assigned and available.
+    Should already be assigned and available.  The definition is available by

+  @details This is the same algorithm used to hash records in
+  [Data Controller for SAS](https://datacontroller.io) (free for up
+  to 5 users).
+
+  It is not designed to be efficient - it is designed to be effective,
+  given the range of edge cases (large floating points, special missing
+  numerics, thousands of columns, very wide columns).
+
+  It can be used only in data step, eg as follows:
+
+      data _null_;
+        set sashelp.class;
+        hashvar=%mp_md5(cvars=name sex, nvars=age height weight);
+        put hashvar=;
+      run;
+
+  Unfortunately it will not run in SQL - it fails with the following message:
+
+  > The width value for HEX is out of bounds. It should be between 1 and 16
+
+  The macro will also cause errors if the data contains (non-special) missings
+  and the (undocumented) `options dsoptions=nonote2err;` is in effect.
+
+  This can be avoided in two ways:
+
+  @li Global option:  `options dsoptions=nonote2err;`
+  @li Data step option: `data YOURLIB.YOURDATASET /nonote2err;`

+
+  This macro is designed to be used as part of a wider load / ETL process (such
+  as the one in [Data Controller for SAS](https://datacontroller.io)).
+
+  Specifically, the macro assumes that the base table has already been 'locked'
+  (eg with the mp_lockanytable.sas macro) prior to invocation.  Also, several
+  tables are assumed to exist (names are configurable):
+
+  @li work.staging_table - the staged data, minus the retained key element
+  @li permlib.base_table - the target table to be loaded (**not** loaded by this
+    macro)
+  @li permlib.maxkeytable - optional, used to store load metaadata.
+    The definition is available by running mp_coretable.sas as follows:
+    `mp_coretable(MAXKEYTABLE)`.
+  @li permlib.locktable - Necessary if maxkeytable is being populated. The
+    definition is available by running mp_coretable.sas as follows:
+    `mp_coretable(LOCKTABLE)`.
+
+
+  @param [in] base_lib= (WORK) Libref of the base (target) table.
+  @param [in] base_dsn= (BASETABLE) Name of the base (target) table.
+  @param [in] append_lib= (WORK) Libref of the staging table
+  @param [in] append_dsn= (APPENDTABLE) Name of the staging table
+  @param [in] retained_key= (DEFAULT_RK) Name of RK to generate (should exist on
+    base table)
+  @param [in] business_key= (PK1 PK2) Business key against which to generate
+    RK values.  Should be unique and not null on the staging table.
+  @param [in] check_uniqueness=(NO) Set to yes to perform a uniqueness check.
+    Recommended if there is a chance that the staging data is not unique on the
+    business key.
+  @param [in] maxkeytable= (0) Provide a maxkeytable libds reference here, to
+    store load metadata (maxkey val, load time).  Set to zero if metadata is not
+    required, eg, when preparing a 'dummy' load. Structure is described above.
+    See below for sample data.

+    |`DC487173.MPE_FILTERANYTABLE `|`filter_rk `|`14 `|`1951053886.8 `|
+  @param [in] locktable= (0) If updating the maxkeytable, provide the libds
+    reference to the lock table (per mp_lockanytable.sas macro)
+  @param [in] filter_str= Apply a filter - useful for SCD2 or BITEMPORAL loads.
+    Example: `filter_str=%str( (where=( &now < &tech_to)) )`
+  @param [out] outds= (WORK.APPEND) Output table (staging table + retained key)

+/**
+  @file
+  @brief Prepares an audit table for stacking (re-applying) the changes.
+  @details When the underlying data from a Base Table is refreshed, it can be
+    helpful to have any previously-applied changes, re-applied.
+
+    Such situation might arise if you are applying those changes using a tool
+    like [Data Controller for SAS®](https://datacontroller.io) - which records
+    all such changes in an audit table.
+    It may also apply if you are preparing a series of specific cell-level
+    transactions, that you would like to apply to multiple sets of (similarly
+    structured) Base Tables.
+
+    In both cases, it is necessary that the transactions are stored using
+    the mp_storediffs.sas macro, or at least that the underlying table is
+    structured as per the definition in mp_coretable.sas (DIFFTABLE entry)
+
+    <b>This</b> macro is used to convert the stored changes (tall format) into
+    staged changes (wide format), with base table values incorporated (in the
+    case of modified rows), ready for the subsequent load process.
+
+    Essentially then, what this macro does, is turn a table like this:
+
+|KEY_HASH:$32.|MOVE_TYPE:$1.|TGTVAR_NM:$32.|IS_PK:best.|IS_DIFF:best.|TGTVAR_TYPE:$1.|OLDVAL_NUM:best32.|NEWVAL_NUM:best32.|OLDVAL_CHAR:$32765.|NEWVAL_CHAR:$32765.|

+
+    As you might expect, there are a bunch of extra features and checks.
+
+    The macro supports both SCD2 (TXTEMPORAL) and UPDATE loadtypes. If the
+    base table contains a PROCESSED_DTTM column (or similar), this can be
+    ignored by declaring it in the `processed_dttm_var` parameter.
+
+    The macro is also flexible where columns have been added or removed from
+    the base table UNLESS there is a change to the primary key.
+
+    Changes to the primary key fields are NOT supported, and are likely to cause
+    unexpected results.
+
+    The following pre-flight checks are made:
+
+    @li All primary key columns exist on the base table
+    @li There is no change in variable TYPE for any of the columns
+    @li There is no reduction in variable LENGTH below the max-length of the
+      supplied values
+
+    Rules for stacking changes are as follows:
+
+    <table>
+    <tr>
+      <th>Transaction Type</th><th>Key Behaviour</th><th>Column Behaviour</th>
+    </tr>
+    <tr>
+      <td>Deletes</td>
+      <td>
+        The row is added to `&outDEL.` UNLESS it no longer exists
+        in the base table, in which case it is added to `&errDS.` instead.
+      </td>
+      <td>
+        Deletes are unaffected by the addition or removal of non Primary-Key
+        columns.
+      </td>
+    </tr>
+    <tr>
+      <td>Inserts</td>
+      <td>
+        Previously newly added rows are added to the `outADD` table UNLESS they
+        are present in the Base table.<br>In this case they are added to the
+        `&errDS.` table instead.
+      </td>
+      <td>
+        Inserts are unaffected by the addition of columns in the Base Table
+        (they are padded with blanks).  Deleted columns are only a problem if
+        they appear on the previous insert - in which case the record is added
+        to `&errDS.`.
+      </td>
+    </tr>
+    <tr>
+      <td>Updates</td>
+      <td>
+        Previously modified rows are merged with base table values such that
+        only the individual cells that were _previously_ changed are re-applied.
+        Where the row contains cells that were not marked as having changed in
+        the prior transaction, the 'blanks' are filled with base table values in
+        the `outMOD` table.<br>
+        If the row no longer exists on the base table, then the row is added to
+        the `errDS` table instead.
+      </td>
+      <td>
+        Updates are unaffected by the addition of columns in the Base Table -
+        the new cells are simply populated with Base Table values.  Deleted
+        columns are only a problem if they relate to a modified cell
+        (`is_diff=1`) - in which case the record is added to `&errDS.`.
+      </td>
+    </tr>
+    </table>

+  @brief Converts deletes/changes/appends into a single audit table.
+  @details When tracking changes to data over time, it can be helpful to have
+    a single base table to track ALL modifications - enabling audit trail,
+    data recovery, and change re-application.  This macro is one of many
+    data management utilities used in [Data Controller for SAS](
+    https:datacontroller.io) - a comprehensive data ingestion solution, which
+    works on any SAS platform (Viya, SAS 9, Foundation) and is free for up to 5
+    users.
+
+    NOTE - this macro does not validate the inputs. It is assumed that the
+    datasets containing the new / changed / deleted rows are CORRECT, contain
+    no additional (or missing columns), and that the originals dataset contains
+    all relevant base records (and no additionals).
+
+    Usage:
+
+        data work.orig work.deleted work.changed work.appended;
+          set sashelp.class;
+          if _n_=1 then do;

+          end;
+          else if _n_=2 then do;
+            output work.orig;
+            age=99;

+          end;
+          else do;
+            name='Newbie';

+          ,outds=work.final
+          ,mdebug=1
+        )
+
+  @param [in] libds Target table against which the changes were applied
+  @param [in] origds Dataset with original (unchanged) records.  Can be empty if
+    only appending.
+  @param [in] key Space seperated list of key variables
+  @param [in] delds= (0) Dataset with deleted records
+  @param [in] appds= (0) Dataset with appended records
+  @param [in] modds= (0) Dataset with modified records
+  @param [out] outds= (work.mp_storediffs) Output table containing stored data.
+    DDL as follows:  %mp_coretable(DIFFTABLE)
+
+  @param [in] processed_dttm= (0) Provide a datetime constant in relation to
+    the actual load time.  If not provided, current timestamp is used.
+  @param [in] mdebug= set to 1 to enable DEBUG messages and preserve outputs
+  @param [out] loadref= (0) Provide a unique key to reference the load,
+    otherwise a UUID will be generated.

-/**
-  @file
-  @brief Provides a replacement for the stpsrv_header function
-  @details The stpsrv_header is normally a built-in function, used to set the
-  headers for SAS 9 Stored Processes as documented here:
-  https://go.documentation.sas.com/doc/en/itechcdc/9.4/stpug/srvhead.htm
-
-  The purpose of this custom function is to provide a replacement when running
-  similar code as a web service against
-  [sasjs/server](https://github.com/sasjs/server).  It operates by creating a
-  text file with the headers.  The location of this text file is determined by
-  a macro variable (`sasjs_stpsrv_header_loc`) which needs to be injected into
-  each service by the calling process, eg:
-
-      %let sasjs_stpsrv_header_loc = C:/temp/some_uuid/stpsrv_header.txt;
-
-  Note - the function works by appending headers to the file.  If multiple same-
-  named headers are provided, they will all be appended - the calling process
-  needs to pick up the last one.  This will mean removing the attribute if the
-  final record has an empty value.
-
-  The function takes the following (positional) parameters:
-
-  | PARAMETER | DESCRIPTION |
-  |------------|-------------|
-  | name $  | name of the header attribute to create|
-  | value  $  | value of the header attribute|
-
-  It returns 0 if successful, or -1 if an error occured.
-
-  Usage:
-
-      %let sasjs_stpsrv_header_loc=%sysfunc(pathname(work))/stpsrv_header.txt;
-
-      %mcf_stpsrv_header(wrap=YES, insert_cmplib=YES)
-
-      data _null_;
-        rc=stpsrv_header('Content-type','application/text');
-        rc=stpsrv_header('Content-disposition',"attachment; filename=file.txt");
-      run;
-
-      data _null_;
-        infile "&sasjs_stpsrv_header_loc";
-        input;
-        putlog _infile_;
-      run;
-
-
-  @param [out] wrap= (NO) Choose YES to add the proc fcmp wrapper.
-  @param [out] insert_cmplib= (NO) Choose YES to insert the package into the
-    CMPLIB reference.
-  @param [out] lib= (work) The output library in which to create the catalog.
