PL/I provides a number of user exits that allow you to
customize the PL/I product to suit your needs. The
workstation PL/I and PL/I for AIX
products supply default exits and the associated source files.
If you want the exits to perform functions that are different
from those supplied by the default exits, we recommend that you
modify the supplied source files as appropriate.
The types of files provided include:
- PL/I source files with the extension PLI that are located in
..\samples.
- PL/I include files with the extension CPY that are located in ..\include. When compiling the user exits, make sure to set the INCLUDE
or IBM.SYSLIB environment variables so that the CPY files can be
found.
- Linker definition files with the extension DEF that are located
in ..\samples.
- Control files (if applicable to the exit) with the extension
INF that are located in ..\samples. When using the user exits, make sure the directory containing
the INF files is specified using the appropriate environment variables
(usually DPATH).
