Where I read:
It would be useful is the current limit would be raised to a higher value,
and the logical value would be 32767, the maximum 2-byte signed value.
Ummm...
32760 for RECFM=FB
32756 for RECFM=VB
???? for RECFM=VBS (but does SuperC support VBS?)
???? for UNIX files
But I believe for UNIX, SUPERC uses QSAM, which imposes the limits above.
Underreaching. SuperC should impose *no* limit of its own, but simply
OPEN OLDDD and NEWDD and reflect any errors reported by OPEN.
Access method limitations are documented in "Using Data Sets".
(When last I tried, SuperC accepted allocated UNIX files for OLDD
and NEWDD, but not for DELDD. Go figger.)
Updated to:
It would be useful is the current limit would be raised to a higher value, and
tentative maximum values could be 27998, the non-spanned maximum blocksize for
3390 devices, or 32767, the maximum signed value for a halfword, but even a
value of 1024 or 4096 would be more helpful.
