The REXX language imposes no limit on the number of subroutine call or function invocation parameters, but allows implementations to specify limits. TSO/E has the limit of 20. For function invocation see "z/OS TSO/E REXX Reference, chapter 4 "Functions", topic "Sntax": "There can be up to an implementation-defined maximum number of expressions, separated by commas, between the parentheses. In TSO/E, the implementation maximum is up to 20 expressions." Search for "20 expressions" to find other places, such as the CALL instruction, etc. -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
