("both forms" = source text and run-time text I/O)

But there would be a particular EBCDIC code representing the Latin-1
source-text linefeed character.  The real issue is that the
line-terminator would be implicit in the "logical record length" (LRECL).
However, it appears to follow from RM95 2.2(2) that *both* non-tab format
effectors (i.e., the EBCDIC codes representing the Latin-1 format
effectors) and the end-of-record would have to be recognized as the
end of a source line, so the net effect in cases such as a FF embedded in
a comment would be the same as on non-EBCDIC-based systems.
