What about the HLASM TK SP Macros?
I coded yesterday for a test, growing out of an example I posted
on IBM-MAIN:
...
RC = BPXWDYN( 'alloc rtddn(DDX) rtdsn(DSX) rtvol(VLX) new delete' ,
word( 'dsn('userid()'.TEMP.LMTEST)' ,
'unit(VIO)', 1 ) ,
'dsorg(PS) recfm(V,B) lrecl(137) msg(WTP)' )
...
I can change the word number either to 1 for a DASD data set
or to 2 for VIO. Cleary I miss the facility of conditional
expressions in Rexx.
