So, is it completely equivalent, as my experiment seems to show,
to specify any of:
//SYSUT2 DD UNIT=SYSALLDA,SPACE=(1,100),AVGREC=M,
//SYSUT3 DD UNIT=SYSALLDA,SPACE=(100,1),AVGREC=M,
//SYSUT4 DD UNIT=SYSALLDA,SPACE=(1,102400),AVGREC=K,
//SYSUT5 DD UNIT=SYSALLDA,SPACE=(20480,5),AVGREC=K,
... (all with RECFM=FB,LRECL=1,DSORG=PS)?
If so, why doesn't the C/I let me specify, simply:
//SYSUT6 DD UNIT=SYSALLDA,SPACE=(1,102400000),AVGREC=U,
... and do the funky factoring itself (after all, it's closer to
the computer than I am)? Instead, it gives me:
8 IEF642I EXCESSIVE PARAMETER LENGTH IN THE SPACE FIELD
Maybe someday, when all supported processors have 64-bit
arithmetic? (But not needed for the above example.)
