This is of course for a COBOL BATCH MAIN program.

Subject: Re: Determining number of Parameters passed to a COBOL program
"Is there a way to determine how many parameters are being passed into a
COBOL program?"
It all depends on the convention you employ for passing parameters. The most
common is to pass the PARM string as a comma delimited string. So in the
simplest form, the number of parameters is the number of commas plus one.
In the example" //S1 EXEC PGM=P1,PARM='ABC,12345,X87,,55' "you have five
parameters, one of which is the null string.
Typically you use the COBOL UNSTRING statement to parse the PARM string looking
for delimiters.
The PARM string is typically declared like this:
LINKAGE SECTION.
01 LS-PARM.
05 LS-PARM-LEN PIC S9(4) COMP.
05 LS-PARM-TXT PIC X(100).
PROCEDURE DIVISION USING LS-PARM.
