# The BasePlus package [ver. 1.26.1] ###############################################
The **BasePlus** package implements useful
functions and functionalities I miss in the BASE SAS.
It is inspired by various people, e.g.
- at the SAS-L discussion list
- at the communities.sas.com (SASware Ballot Ideas)
- at the Office...
- etc.
Kudos to all who inspired me to generate this package:
*Mark Keintz*,
*Paul Dorfman*,
*Richard DeVenezia*,
*Christian Graffeuille*,
*Allan Bowe*,
*Anamaria Calai*,
*Michal Ludwicki*,
*Quentin McMullen*,
*Kurt Bremser*.

# Content description ############################################################################################
## >>> `%getVars()` macro: <<< #######################
The getVars() and QgetVars() macro functions
allow to extract variables names form a dataset
according to a given pattern into a list.
The getVars() returns unquoted value [by %unquote()].
The QgetVars() returns quoted value [by %superq()].
See examples below for the details.
The `%getVars()` macro executes like a pure macro code.
### SYNTAX: ###################################################################
The basic syntax is the following, the `<...>` means optional parameters:
~~~~~~~~~~~~~~~~~~~~~~~sas
%getVars(
ds
<,sep=>
<,pattern=>
<,varRange=>
<,quote=>
<,mcArray=>
)
~~~~~~~~~~~~~~~~~~~~~~~
**Arguments description**:
1. `ds` - *Required*, the name of the dataset from
which variables are to be taken.
* `sep = %str( )` - *Optional*, default value `%str( )`,
a variables separator on the created list.
* `pattern = .*` - *Optional*, default value `.*` (i.e. any text),
a variable name regexp pattern, case INSENSITIVE!
* `varRange = _all_` - *Optional*, default value `_all_`,
a named range list of variables.
* `quote =` - *Optional*, default value is blank, a quotation
symbol to be used around values.
* `mcArray=` - *Optional*, default value is blank.
1) When *null* - the macro behaves like a macro function
and returns a text string with variables list.
2) When *not null* - behaviour of the macro is altered.
In such case a macro array of selected variables, named
with `mcArray` value as a prefix, is created.
Furthermore a macro named as `mcArray` value is generated.
(see the macroArray package for the details).
When `mcArray=` parameter is active the `getVars` macro
cannot be called within the `%put` statement. Execution like:
`%put %getVars(..., mcArray=XXX);` will result with
an Explicit & Radical Refuse Of Run (aka ERROR).
### EXAMPLES AND USECASES: ####################################################

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
d) coma separated single quote list:

%let z = %unquote(&y.);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

## >>> `%symdelGlobal()` macro: <<< #######################
The `%symdelGlobal()` macro deletes all global macrovariables
created by the user. The only exceptions are read only variables
and variables the one which starts with SYS, AF, or FSP.
In that case a warning is printed in the log.
One temporary global macrovariable `________________98_76_54_32_10_`
and a dataset, in `work` library, named `_%sysfunc(datetime(),hex7.)`
are created and deleted during the process.

The number of "sparse distinct data values" is set to `100'000` to
use the hash sort instead of the quick sort.
E.g. when number of unique values for sorting is less then

and their count and sort them.
*Caution!* Array parameters to subroutine calls *must* be 1-based.

## >>> `quickSortHashSDDV()` subroutine: <<< #######################
The **quickSortHashSDDV()** subroutine is an alternative to the
`CALL SORTN()` subroutine for 1-based big arrays (i.e. `> 10'000'000` elements)
when memory used by `call sortn()` may be an issue.
For smaller arrays the memory footprint is not significant.
The subroutine is based on an iterative quick sort algorithm
implemented in the `qsortInCbyProcProto()` *C* prototype function.
The number of "sparse distinct data values" (argument `SDDV`) may
be adjusted to use the hash sort instead of the quick sort.
E.g. when number of unique values for sorting is less then
some *N* then an ordered hash table is used to store the data
and their count and sort them.
*Caution!* Array parameters to subroutine calls *must* be 1-based.
*Note!* Due to improper memory reporting/releasing for hash
tables in FCMP procedure the report memory used after running
the function may not be in line with the RAM memory required
for processing.

to calculate result of the function on taken elements.
When one of the lists is shorter then elements are "reused" starting
from the beginning.
The zipEvalf() returns unquoted value [by %unquote()].
The QzipEvalf() returns quoted value [by %superq()].
See examples below for the details.
The `%QzipEvalf()` macro executes like a pure macro code.

## >>> `%zipEvalf()` macro: <<< #######################
The zipEvalf() and QzipEvalf() macro functions
allow to use a function on elements of pair of
space separated lists.
For two space separated lists of text strings the corresponding
elements are taken and the macro applies a function, provided by user,
to calculate result of the function on taken elements.
When one of the lists is shorter then elements are "reused" starting
from the beginning.
The zipEvalf() returns unquoted value [by %unquote()].
The QzipEvalf() returns quoted value [by %superq()].
See examples below for the details.
The `%zipEvalf()` macro executes like a pure macro code.

### BOX-AND-WHISKERS PLOT: ###################################################################
The box-and-whiskers plot has the following interpretation:
- left vertical bar indicates the minimum,
- left whisker line starts at `max(Q1 - 1.5IQR, minimum)` and ends at lower quartile (Q1),
- diamond indicates mean,
- vertical bar inside of the box indicates median,
- right whisker line starts at upper quartile (Q3) and ends at `min(Q3 + 1.5IQR, maximum)`,
- right vertical bar indicates the maximum.
With above setup it may happen that
there is a gap between the minimum marker and the beginning of the left whisker
or
there is a gap between the end of the right whisker and the maximum marker.
See examples below.

## >>> `%LDSN()` macro: <<< #######################
The LDSN (Long DataSet Names) macro function
allows to use an "arbitrary" text string to name a dataset.
The LDSN macro has some limitation described below, to overcome them
another macro, with different name: LDSNM (Long DataSet Names Modified)
was created. See its description to learn how to use it.
---
The idea for the macro came from the following story:
Good friend of mine, who didn't use SAS for quite some time,
told me that he lost a few hours for debugging because
he forgot that the SAS dataset name limitation is 32 bytes.
I replied that it shouldn't be a problem to do a workaround
for this inconvenience with a macro and the `MD5()` hashing function.
I said: *The macro should take an "arbitrary string" for a dataset
name, convert it, with help of `MD5()`, to a hash digest, and
create a dataset with an "artificial" `hex16.` formated name.*
Starting with something like this:
~~~~~~~~~~~~~~~~~~~~~~~sas
data %LDSN(work. peanut butter & jelly with a hot-dog in [a box] and s*t*a*r*s (drop = sex rename=(name=first_name) where = (age in (12,13,14))) );
set sashelp.class;
run;
~~~~~~~~~~~~~~~~~~~~~~~
the macro would do:
~~~~~~~~~~~~~~~~~~~~~~~sas
%sysfunc(MD5(peanut butter & jelly with a hot-dog in [a box] and s*t*a*r*s), hex16.)
~~~~~~~~~~~~~~~~~~~~~~~
and (under the hood) return and execute the following code:
~~~~~~~~~~~~~~~~~~~~~~~sas
data work.DSN_41D599EF51FBA58_(drop = sex rename=(name=first_name) where = (age in (12,13,14))) ;
set sashelp.class;
run;
~~~~~~~~~~~~~~~~~~~~~~~
Also in the next data step user should be able to do:
~~~~~~~~~~~~~~~~~~~~~~~sas
data my_next_data_step;
set %DSN(work. peanut butter & jelly with a hot-dog in [a box] and s*t*a*r*s);
run;
~~~~~~~~~~~~~~~~~~~~~~~
and work without the "dataset-name-length-limitation" issue.
---
See examples below for the details.
The `%LDSN()` macro executes like a pure macro code.
**Known "Limitations":**
- dataset name _cannot_ contain dots (`.`) since they are used as separators!
- dataset name _cannot_ contain round brackets(`(` and `)`) since they are used as separators
(but `[]` and `{}` are allowed)!
- dataset name _cannot_ contain unpaired quotes (`'` and `"`),
text: `a "hot-dog"` is ok, but `John's dog` is not!
**Behaviour:**
- dataset name text is *converted to upcase*
- dataset name text *leading and trailing spaces are ignored*,
e.g. the following will give the same hash digest:
`%ldsn(work.test)`, `%ldsn( work.test)`, `%ldsn(work.test )`,
`%ldsn(work .test)`, `%ldsn(work. test)`, `%ldsn(work . test)`.
- macro calls of the form:
`data %LDSN(); run;`, `data %LDSN( ); run;`, `data %LDSN( . ); run;` or even
`data %LDSN( . (keep=x)); run;` are resolved to empty string, so the result is
equivalent to `data; run;`
### SYNTAX: ###################################################################
The basic syntax is the following, the `<...>` means optional parameters:
~~~~~~~~~~~~~~~~~~~~~~~sas
%LDSN(
arbitrary text string (in line with limitations)
)
~~~~~~~~~~~~~~~~~~~~~~~
The text string is concider as *"fully qualified dataset name"*, i.e. macro
assumes it may contain library as prefix and data set options as sufix.
See the `%LDsNm()` macro for comparison.

## >>> `%LDSNM()` macro: <<< #######################
The LDSNM (Long DataSet Names Modified) macro function
allows to use an "arbitrary" text string to name a dataset.
The LDSN macro had some limitation (see its documentation), to overcome them
another `%LDSNM()` (Long DataSet Names Modified) macro was created.
The main idea behind the `%LDSNM()` is the same as for `%LDSN()` - see the description there.
---
The `%LDSNM()` macro works differently than the `%LDSN()` macro.
The `%LDSN()` macro assumes that *both* libname and dataset options *are*
be passed as elements **inside** the macro argument, together with the data set name. E.g.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
data %LDSN( WORK.peanut butter & jelly with a hot-dog in [a box] and s*t*a*r*s (drop = sex) );
set sashelp.class;
run;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The `%LDSNM()` macro, in contrary, assumes that both libname and dataset options are
passed **outside** the macro parameter, i.e.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
data WORK.%LDSNM( peanut butter & jelly with a hot-dog in [a box] and s*t*a*r*s ) (drop = sex);
set sashelp.class;
run;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This approach overcomes some limitations the LDSN has.
The **additional** feature of the `%LDSNM()` is that when the macro is called,
a global macrovariable is created.
The macro variable name is the text of the hashed data set name.
The macro variable value is the text of the unhashed data set name (i.e. the argument of the macro).
For example the following macro call:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
data %LDSNM(John "x" 'y' dog);
set sashelp.class;
where name = 'John';
run;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
creates macro variable with name `DSN_BF1F8C4D6495B34A_` and with value: `JOHN "X" 'Y' DOG`.
The macrovariable is useful when combined with `symget()` function and
the `indsname=` option to get the original text string value back,
like in this example:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
data test;
set %LDSNM(John "x" 'y' dog) indsname = i;
indsname = symget(scan(i,-1,"."));
run;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
See examples below for the details.
---
The `%LDSN()` macro executes like a pure macro code.
**Known "Limitations":**
- dataset name _cannot_ contain _unpaired_ round brackets(`(` and `)`)
(but unmatched `[]` and `{}` are allowed)!
- dataset name _cannot_ contain _unpaired_ quotes (`'` and `"`),
text: `a "hot-dog"` is ok, but `John's dog` is not!
**Behaviour:**
- dataset name text is *converted to upcase*
- dataset name text *leading and trailing spaces are ignored*,
e.g. the following will give the same hash digest:
`%ldsn(test)`, `%ldsn( test)`, `%ldsn(test )`.
- macro calls of the form:
`data %LDSN(); run;` or `data %LDSN( ); run;` are resolved
to empty string, so the result is equivalent to `data; run;`
- created macrovariable is _global_ in scope.

## >>> `%dirsAndFiles()` macro: <<< #######################
The `%dirsAndFiles()` macro allows to extract info about all files
and subdirectories of a given `root` directory.
The extracted info may be just a list of files and subdirectories or, if
the `details=` parameter is set to 1, additional operating system information
is extracted (information is OSS dependent and gives different results for Linux
and for Windows)
The extracted info can be narrowed down to files (`keepFiles=1`) or to
directories (`keepDirs=1`) if need be.
The extracted info can be presented in wide or long format (`longFormat=1`).
The extracted info for files can be narrowed down to only files with particular
extension, for example: `fileExt=sas7bdat`.
The extracted info can be narrowed down maximal path depth
by setting up the `maxDepth=` parameter.
See examples below for the details.

## >>> `%findDSwithVarVal()` macro: <<< #######################
The findDSwithVarVal() macro searches for all
datasets (available for a given session) containing
a variable of a given value.
The value search is case sensitive - but can be altered with `IC=` parameter.
The value search keeps leading blanks - but can be altered with `TB=` parameter.
The value search compares full value - but can be altered with `CTS=` parameter.
The default variable type is `char`, the `type=` parameter allows
to change it (possible values are `char` and `num`), the parameter is case sensitive.
Only datasets are searched, views are not included.
During the process two temporary datasets named:
`WORK._` (single underscore) and `WORK.__` (double underscore)
are generated. The datasets are deleted at the end of the process.
By default search results are stored in the `WORK.RESULT` dataset.
Name of the dataset can be altered with `result=` parameter.
The dataset with result contains two variables:
`datasetName` - names of datasets,
`firstObservation` - the firs occurrence of the value.
See examples below for the details.
The `%findDSwithVarVal()` macro does not execute as a pure macro code.
### SYNTAX: ###################################################################

~~~~~~~~~~~~~~~~~~~~~~~
**Arguments description**:
1. `variable` - *Required*, name of variable to be searched.
2. `value` - *Required*, the value to be searched.
*. `type` - *Optional*, default value is `char`.
Indicates which type is the searched value.
Possible values are `char` and `num`,
the parameter is case sensitive.
*. `ic` - *Optional*, "Ignore Cases", default value is `0`.
Indicates should the search ignore cases of the text values.
Possible values are `0` and `1`.
*. `tb` - *Optional*, "Trim Blanks", default value is `0`.
Indicates should the search trim leading and trailing
blanks of the text values.
Possible values are `0` and `1`.
*. `cts` - *Optional*, "Compare To Shorter", default value is `0`.
IF set to `1` execute value comparison as `=:` for the text value.
Possible values are `0` and `1`.
See examples.
*. `lib` - *Optional*, default value is missing.
If not empty narrows the search to a particular library.
*. `result` - *Optional*, default value is `WORK.RESULT`.
Is the name of the dataset with results.

## >>> `%getTitle()` macro: <<< #######################
The getTitle() macro extract text of titles or footnotes
into a delimited list.
Titles/footnotes numbers can be selected with the `number` argument.
Only the text of a title or footnote is extracted.
Author of the original code is: Quentin McMullen (`qmcmullen.sas@gmail.com`).
See examples below for the details.
The `%getTitle()` macro executes like a pure macro code.
### SYNTAX: ###################################################################
The basic syntax is the following, the `<...>` means optional parameters:
~~~~~~~~~~~~~~~~~~~~~~~sas
%getTitle(
< number>
<,type=>
<,dlm=>
<,qt=>
)
~~~~~~~~~~~~~~~~~~~~~~~
**Arguments description**:
1. `number` - *Optional*, default value is empty,
indicates numbers of titles to be extracted.
Space separated list is expected.
If empty or `_ALL_` extract all non-missing.
*. `type` - *Optional*, default value is `T`.
Indicates which type is the searched.
`T` fro title, `F` for footnote.
*. `dlm` - *Optional*, "DeLiMiter", default value is `|` (pipe).
Possible values are: `| \ / , . ~ * # @ ! + - _ : ?`
or `s` for space, `c` for comma, `d` for semicolon.
*. `qt` - *Optional*, "QuoTes", default value is empty.
Use `%str()` for single quote symbol (e.g. `%str(%")`).
If there are multiple symbols, only the first and the
second are selected as a leading and trailing one,
e.g. `qt=""` gives `"title1 text" "title2 text" ... `.
