SAS Packages Framework, version `20260602` Changes: - New macro: `%requestPackage()`; - Error fix for `githubRepo=` selection in the `%installPackage()` macro; - check for already loaded packages added to the `%loadPackage()` macro to avoid unnecessary re-loading; - update in `CMPLIB` cleaning for the `%unloadPacjkage()` macro.

des='SAS Packages Framework internal macro. Executable only inside selected SPF macros. Macro generates 4GL code that forces V7 compatybility for user provided data set names. Version 20260602.';
|
|
/* The macro can be called only inside a data step. */
|
|
/****************************************************************************
|
|
### Parameters:
|
|
|
|
`mcParam` - name of a macro parameter holding user provided data set name
|
|
|
|
### Behavior:
|
|
|
|
Description:
|
|
The 4GL code SYMGETs macro variable value, SCANs only first
|
|
part of the string in case there are parenthesis "()" in it.
|
|
Then it COMPRESSes the string and keep _only_ digits, letters,
|
|
underscore, and period. All periods are TRANSLATEd to spaces.
|
|
If created string is not empty its last chunk is SCANned for
|
|
data set name, the second to last chunk is SCANned for libname
|
|
(if empty then "work" is used). First character of LIB and DS
|
|
variables is checked, if it is a digit, then underscore is added.
|
|
At the end the LIB and DS are concatenated and upper cased.
|
|
case letters.
|
|
|
|
Examples:
|
|
|
|
abc.xyz -> ABC.XYZ
|
|
ABC.XYZ(obs=42) -> ABC.XYZ
|
|
XYZ -> WORK.XYZ
|
|
abc. -> WORK.ABC
|
|
.XYZ -> WORK.XYZ
|
|
123.456 -> _123._456
|
|
A#B.x$y -> AB.XY
|
|
|
|
Usecase:
|
|
Inside a macro for value check
