> Any ideas on what's wrong? That's interesting, I've been trying to find out why, from time to time, I get mail with two 'Reply-To:' fields and no 'Sender:' field. It was never quite clear to me whether this was a MAILER, CP or CMS problem, but it seems that you got the same thing in LISTSERV: > Output from LSVPUNCH starts on next line. > 1/line 1 <<<- This duplication doesn't always occur. Sometimes --> That line should have been the ID line. > 1/line 1 <<<- the first line is just blank. > 1/line 2 > 1/line 3 > END/ > Output from LSVPUNCH ends on line above. Most probable cause: the PUNCHC macro returns control to the application before getting the channel end from the virtual punch, or before issuing the SIO (gasp)! The buffer is re-used by the application (for LSVPUNCH this is definitely the case) and the "wrong" data gets picked up when the I/O is processed. So I would suspect a CMS bug rather than a CP bug.
