Also note that output from command files invoked by DELIVER can be captured in a file by using the /OUTPUT qualifier: ! Execute a command file with logging * * * A E @DO_SOMETHING.COM/OUTPUT=DO_SOMETHING.LOG DELIVER does watch for users sending messages to themselves and then tries to be somewhat more informative than is usual about any errors it finds in MAIL.DELIVERY files. 2. Much of the line and symbol processing done by DELIVER uses 252 character buffers. In particular, parameters in MAIL.DELIVERY files are limited to a maximum of 252 characters each. Most lines processed by DELIVER are limited to PMDF's usual 1024 character maximum. Lines output to command files are a special case; DELIVER must respect DCL's builtin 256- character line length limit. This might impose even more severe restrictions on symbol assignments and other commands than DELIVER does. DELIVER silently truncates lines rather than complaining about line lengths.
