The PRINTCARDS card instructs the VP390 job to print each of the SYSIN lines that it reads to the SYSPRINT, excluding blank lines and comment lines. This is usually only used to document the cards that have been read when sending the SYSPRINT output to support for problem analysis. Enter PRINTCARDS as the first line of the SYSIN dataset member to document all the lines of the SYSIN input.
The PRINTCARDS card can be used multiple times in the SYSIN as a toggle control. The second occurrence of PRINTCARDS will stop the writing to SYSPRINT, the third occurrence will resume the writing, and so forth.
