Hey SAS-C,
Just FYI,
Bart
SAS Packages Framework, version 20221212, is here.
Changes in the framework:
New type.
New type CASLUDF for CASL User Defined Functions added to the framework.
Rules for adding CASL User Defined Functions to a package are the same as those for FCMP functions (FUNCTIONS), user formats (FOTMATS) or IML modules (IMLMODULE) types, and in line with general rules:
- one file one function,
- file contains only function definition e.g.,
function myFunction(x, y, z);
result = x + y + z;
return (result);
end func;
CASL UDFs are loaded through a dedicated utility macro generated at the loading process and described below.
New utility macros.
If a package contains IML modules or CASL user defined functions additional utility macros for IML Modules and CASL UDFs are generated when package is loaded.
Macros are generated with the following names: %<packageName>IML() and %<packageName>CASLudf(). Their purpose is to make loading of Modules or UDFs (with potentially multiple dependencies) easy in Proc IML and Proc CAS.
Run them, accordingly, as the first line in the Proc IML or Proc CAS to access the package content.
For Proc IML the use is as follows:
proc IML;
%<packageName>IML()
<... your code using IML modules from the package ...>
quit;
For Proc CAS the use is as follows:
proc CAS;
%<packageName>CASLudf()
<... your code using CASL UDFs from the package ...>
quit;
If a utility macro is generated appropriate note and a code snippet is printed in the log of the package loading process.
In 99% cases macros are used with default parameters values but, in case when deeper insight about macros parameters is needed, help info is printed in the log when the following code is run:
%<packageName>IML(list=HELP)
or
%<packageName>CASLudf(list=HELP)
If created, those macros are automatically deleted when the %unloadPackage() macro is run.
Other.
Documentation updated.
Minor bugfix.
