 - Mandatory parameters should be positional, all optional parameters should be keyword (var=) style.
 - All dataset references must be 2 level (eg `work.blah`, not `blah`). This is to avoid contention when options [DATASTMTCHK](https://support.sas.com/documentation/cdl/en/lrdict/64316/HTML/default/viewer.htm#a000279064.htm)=ALLKEYWORDS is in effect.
 - 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
+

+  @brief Create a smaller version of a dataset, without data loss
+  @details This macro will scan the input dataset and create a new one, that

+
+  Inspiration was taken from [How to Reduce the Disk Space Required by a
+  SAS® Data Set](https://www.lexjansen.com/nesug/nesug06/io/io18.pdf) by
+  Selvaratnam Sridharma.  The end of the referenced paper presents a macro named
+  "squeeze", hence the nomenclature.
+
+  Usage:
+
+      data big;
+        length my big $32000;
+        do i=1 to 1e4;
+          my=repeat('oh my',100);

+      run;
+
+      %mp_ds2squeeze(work.big,outds=work.smaller)
+
+  The following will also be printed to the log (exact values may differ
+  depending on your OS and COMPRESS settings):
+
+  > MP_DS2SQUEEZE: work.big was  625MB
+
+  > MP_DS2SQUEEZE: work.smaller is    5MB

   @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

+
-  the data therein.
+  @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)

+/**
+  @file
+  @brief Generate and apply retained key values to a staging table
+  @details This macro will populate a staging table with a Retained Key based on
+  a business key and a base (target) table.
+
+  Definition of retained key ([source](
+    http://bukhantsov.org/2012/04/what-is-data-vault/)):
+
+  > The retained key is a key which is mapped to business key one-to-one. In
+  > comparison,  the surrogate key includes time and there can be many surrogate
+  > keys corresponding to one business key. This explains the name of the key,
+  > it is retained with insertion of a new version of a row while surrogate key
+  > is increasing.
+
+  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.
+    |KEYTABLE:$32.|KEYCOLUMN:$32.|MAX_KEY:best.|PROCESSED_DTTM:E8601DT26.6|
+    |---|---|---|---|
+    |`DC487173.MPE_SELECTBOX `|`SELECTBOX_RK `|`55 `|`1950427787.8 `|
+    |`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)
