The PERFORM File Before using the PERFORM statement on the HP 260, create a "perform file" containing the commands and user input you want processed in perform mode. The perform file must be a DATA file containing ASCII string data. The records can include 160 characters. The statements in the perform file execute one at a time, in order when you run the file in perform mode. The perform file can include HP 260 commands, MPE commands, BASIC/260 statements, user input or prompts from programs, and special perform commands when you use it with DSN/DS. Perform commands are preceded by a colon. (Do not precede MPE commands with colons.) To run the file automatically, use the "UNATTENDED" statement at the beginning of the perform file.
