That's not exactly true. IIRC, I've submitted JCL statements in records longer
than
80 bytes; columns 73 and beyond are quietly ignored. So 72-byte records would
be
more accurate than 80-byte.

Does it state an upper limit?
Does it explain how the LRECL and RECFM merged into the DCB at OPEN are
determined? I've submitted an RCF on this and the information has not been
added to the manual.

TSO SUBMIT fails with an error if the input data set is other than RECFM=FB
LRECL=80.
This could be changed with negligible compatibility impact to allocate INTRDR
with the
attributes of the input data set and proceed successfully.
(Also on my wish list is that SUBMIT have an INDD() option so I could pipe
from a UNIX process.)
I suspect that ISPF SUBMIT copies its input to a RECFM=FB LRECL=80 data set
(sometimes
with SPACE problems). Changing to submit directly to INTRDR allocated with
attributes of
the input data set would have some compatibility impact and would have to be
made optional.
I have a macro that submits an Edit buffer to INTRDR, defaulting to attributes
of the data set
being edited, with option to force to FB 80.

Alas. Truncation should not be quiet; it's data loss. At a minimum,
the user should be given a prompt with options:
Truncate and submit/Retain attributes and submit/Cancel
