Hi,
This reply for your changed program. Even if I mentioned

PARSE ARG NAME alone(1 argument) in REXX program, its accepting both SAI

and MADRAS....

try (note the period/fullt stop)
PARSE ARG NAME .

Why don't follow your own advice Ravi and read TSO/E REXX Reference- Chapter 5. Parsing ...

The '.' is a place holder. In Mike's example he is:

1. Using PARSE to maintain case
2. Using ARG to accept parameter input
3. Accepting one parameter into a variable called NAME the value of which will be everything from the first non-blank character up to the first blank character.
4. Discarding everything beyond the first blank character into the '.' placeholder.

So in this case you are passing the parameters 'Kris Madras' to the rexx 'Hello' and it is putting Kris into NAME and everything else into '.' Be aware also that the parameter buffer is padded with spaces, so if you were to do:

PARSE ARG NAME SURNAME

Then SURNAME would be equal to 'Madras ' (I have not put all the spaces in, just enough to demonstrate the effect.

The period is a useful device for removing these trailing spaces so a more useful PARSE statement in your case would be:

PARSE ARG NAME SURNAME .

Which would put 'Kris' into NAME, 'Madras' into SURNAME and spaces into '.'

You can use multiple period placeholders anywhere in a parse statement to ignore parts of the string you are not interested in.
