LINKAGE= is supported for STORAGE RELEASE in the same way it is
supported for STORAGE OBTAIN.
The LINKAGE keyword has always been present on the STORAGE macro
since its creation in MVS/ESA SP3.1.0, However, the only supported
value was the default of LINKAGE=SYSTEM.
The other LINKAGE values (SVC, BRANCH, GLOBALBRANCH) were added in
z/OS 1.6 (although not documented in the manuals until z/OS 1.7)
to be equivalent to GETMAIN/FREEMAIN RC/RU/VRC/VRU, so that we would
no longer need to add new functions to the GETMAIN/FREEMAIN macros.
If you think the beginning of the chapter seems a little garbled,
try understanding and enhancing the source code for GETMAIN/FREEMAIN.
As always, we recommend sending a note to mhvr...@us.ibm.com
describing any problems you find in the manuals.
