simple macro to read command line arg

Hi all,
I have a very simple macro to read the data from command line.
The below is in a member ‘PARSE’.
/* rexx */
arg input_file
say input_file
I execute this as an edit macro inside the same member as shown:
parse abc
This does not show the input “abc†that I have sent in command line.
Instead it does show a blank line.
Am I missing something here?
Please let me know if you find something wrong in this code/macro execution procedure.
Thanks,
Venkatesh.
