At least support, for consistency:
https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.3.0/com.ibm.zos.v2r3.bpxa400/pathname.htm
... A path name can be up to 1023 characters long, including all directory
names, file names,
and separating slashes. ...
The enhancement should apply to JCL allocation as well as DYNALLOC.
Does any SVC 99 TU exceed 256 characters? Is this a relic of the MVC
instruction?
I'll suggest here, but it might belong in a separate RFE:
o Relative (to current directory) paths. In batch that would be HOME/.
o Tilde expansion: ~/... and ~username/... I've done this easily in Rexx.
