PROG=xx
The two-character identifier xx is appended to PROG to
identify the PROGxx parmlib member. xx can be any two alphanumeric
characters (A-Z, 0-9) or (@, #, or $).
You can also specify multiple PROGxx members on this parameter.
For example, you can specify two active members using the form PROG=(01,02).
Regardless of whether you specify the PROG=xx parameter, the system
always places the following libraries in the APF list:
- SYS1.LINKLIB and SYS1.SVCLIB
- If the APF=xx system parameter is specified, the libraries contained
in IEAAPFxx.
Note: In addition, any module in the link
pack area (pageable LPA, modified LPA, fixed LPA, or dynamic LPA)
will be treated by the system as though it came from an APF-authorized
library. Ensure that you have properly protected SYS1.LPALIB and any
other library that contributes modules to the link pack area to avoid
system security and integrity exposures, just as you would protect
any APF-authorized library.
