"If you use LNKLSTxx instead of PROGxx, during IPL, the system opens and
concatenates each data set in the order it was listed, starting with the
first-specified LNKLSTxx member. The system creates a data extent block (DEB)
that describes the data sets concatenated to SYS1.LINKLIB and their extents.
The extents remain in effect for the duration of the IPL."

Link list allocations from IPL time do not have to hang around forever. There
are several ways to remove an allocation. My favorite way is to code two
SYS1.PARMLIB members and then just issue two MVS commands to bring them in.
Code a PROGLD member with contents:
LNKLST DEFINE NAME(LNKLST02) COPYFROM(CURRENT) LNKLST DELETE NAME(LNKLST02)
DSNAME(SYS2A.PRODUCT.LINKLIB) LNKLST ACTIVATE NAME(LNKLST02)
LNKLST UPDATE JOB(*)
Then code a CSVLLALD member:
REMOVE(SYS2A.PRODUCT.LINKLIB)
Issue commands:
T PROG=LD
F LLA,UPDATE=LD
This method will remove allocations from VLF and LLA address spaces.

Richard,
I didnt read every single post on the topic, but did you say if this is the
SYSRES you are IPL'd from? Or an alternate that isnt supposed to be in use?
Also, saw your comments about the couple of hardcoded datasets in LINKLIST that
you fixed that were pointing at the volume. I thought IPL time linklist hung
around forever regardless of any SET PROG statements that might have been done?
