Hi all
Learning REXX.
How can I pass different no of arguments to a REXX program ?
I have written a small program to read the argument list and print it. I used the following method

numarg = ARG()
say numarg
Do i = 1 to numarg
say 'arg(' || i || ') =' || ARG(i)
end

I am running this program as TSO EX 'PDS.NAME(MEMBER)' '1 2 3'
All my variables 1 2 &3 are getting associated to arg(1). It is showing arg(1) = '1 2 3' and numarg = 1
I want
arg(1) = 1
arg(2) = 2
arg(3) = 3.

Also I should be able to run this program with different set of variables like TSO EX 'PDS.NAME(MEMBER)' '1 2 3 4 5' without changing the program and the output should look like following
arg(1) = 1
arg(2) = 2
arg(3) = 3
arg(4) = 4
arg(5) = 5

Is this possible in REXX?
I tried exploring the PARSE ARG option without any success.

Regards
Bidpar

Instead of parse option, you can use WORDS() function. This will give you no of variables in the input argument (separated by spaces).

Try this:

Sorry, the code was incomplete, Use this.
