Getting Input to a REXX exec

Hi,

How can I get the string that I give following my rexx exec as an input to a variable in the exec. say, when I give

TSO TEST 123

In my program I should capture this 123 in a variable say abc.

Many Thanks

what did You try by yourself...

for example googling
for "passing arguments to a rexx script"
or "passing arguments to a rexx exec"

even looking at the manuals and searching for arguments might be a good idea

if You keep on exploiting rexx You might need the manuals links anyway
so start to get acquainted with them

ok! ok!

Hi Enrico..

I tried googling.. sadly I was not able to open publibz site.. hence posted it..
I tried searching 'passing input to rexx exec'.. Try it for yourself to see if you could find anything useful.

Its not good to assume that everyone try to exploit this forum members.

parsing arguments will usually end in a religion war
there are usually standards and habits to be considered...

keyword style ( a la TSO commands style )
<rexx_script> IN(somefile) OUT(someotherfile)

unix style
<rexx_script_name> --IN=somefile --OUT=someotherfile ( long form )
<rexx_script_name> -I somefile -O someotherfile

positional style
<rexx_script_name> somefile someotherfile

for the third approach You have two ways

parse arg in ou

or ( my preferred, but it' s a personal thing )
parse arg args
if words(args) <> 2 then do
say "expecting two arguments"
exit
end

in = word(args,1)
ou = word(args,2)

or as an alternative

parse var args in ou .

Am teribly sorry for that..

Guess I should improve my googling skills before trying my hands on any mainframe skill..

Sorry If I had offended you.

Pedro..

You got it right.. The problem was with the member name. My bad..

I changed it and it works good now.

Thank you.

I was not offended at all...

/philosophy on - general talk on
I think that it is the person asking that should be more flexible about the reply tone
people replying too often have seen the same question asked over and over
and to keep replying to the same questions is quite <choose an adjective You like>
