Well, sort of. Alas, too many programmers and products remain unaware
that the 80-column limit was relaxed long ago, although larger valuew
are useful only for instream data sets.
But the obsolete 89-column limit is still enforced by the SUBMIT
commands in ISPF, TSO, OMVS, and Rexx.
CDC took the opposite approach, making binary cards disk
block images, somewhat analogous to:
RECFM=VBS,BLKSZE=80
so that disk records readily spanned cards.
