Regarding distribution of non-MAIL files through LISTSERV: Why is it necessary to de-format a formatted spool file at all? If you read a "PUN" spool file with just READCARD to the work disk, and just "PUNCH ... ( NOH" it back out at the end for the destination user, then why would there be any problems. For between-list-server transmission, the pre-formatted card-image deck can be over-formatted in any desired format, and de-formatted back to the original pre-formatted image.
