Formats for OPS/REXX Data Sets

Data sets containing OPS/REXX programs can have RECFM=V or RECFM=F record formats, with or without line numbers. For variable records, OPS/REXX checks columns 1 through 8 of the first line in the program to determine if line numbers exist. For fixed records, OPS/REXX checks the last eight columns of the first record to determine if line numbers exist.

Note: This checking follows standard TSO conventions.

If the first line in the program has no line number, be sure to check that no subsequent lines have numbers. This can occur if someone uses ISPF EDIT to copy lines from a line-numbered program into a program without line numbers.

The maximum logical record length supported is LRECL=255.
