FYI,
Prior to converting from a System-3 to a 4331 running DOS/VS, IBM
dropped a line-mode remote terminal into our shop. This would be about
1981. We edited programs and JCL using it for about 4 months before we
finally got our 4331.
Until this discussion, I had kinda forgotten this experience. Alan's
comments paged those memories back into main storage. Having used a
remote line-mode terminal, I now understand the history of TRUNC 71.

Bummer. Maybe someone from IBM can shed light on the issue.
I speculate that this was to prevent INSERT and CHANGE from overlaying column
72 by accident when editing in line mode. When you're ready to put in
continuation characters, do TRUNC 72 # CL :72 # COVERLAY X # REPEAT n # TRUNC
71.
AYFK‽ I'll assume that was a macro, perhaps a PF key.
Wouldn't it be useful if after marking the continuation it inserted a following
blank line to contain the rest of the statement?
Naturally we all updated our profiles once 3270s showed up, so it turned into a
non-issue.
What had you used previously? A command line editor?
Will the tyranny of the 026 and 701 ever be overthrown? Has anyone submitted
an RFE to incorporate FLOWASM into HLASM; even make it the default?
