Found this in an IBM publication (SA32-0982-00): When you invoke a REXX exec either implicitly or explicitly using the EXEC command. You can pass either one or no arguments to the exec. Thus the ARG instruction in the preceding examples received only one argument. One argument can consist of many words. The argument, if present, will appear as a single string.

Basically, if the code is running under TSO batch or online there is only “1” argument passed to the code. There is a limitation on how long that may be, I think 255 bytes or something like that. As for the number of parameters that is of no concern and neither is the method of separation. If you are indeed passing spaces, commas, or quotes, you will have to code for these. The following would be valid. Ex REXXCODE ‘(‘ab c’), mommy, daddy, ‘1234 main street’, ‘Columbus, oh’, ‘help me’ ’ In the REXX Parse is would look like this PARSE UPPER ARG PARAM_LIST Note: the UPPER is the default PARAM_LIST = (‘AB C’), MOMMY, DADDY, ‘1234 MAIN STREET’, ‘COLUMBUS, OH’, ‘HELP ME’ The code would then have to know what to look for and parse the various parameters from the list. No magic, no rules.

ALERTSN is not seeing any of it. The error message is emitted while ALERTSNB is in control. ALERTSN is never invoked.
