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.
asking what You had done Yourself is nowhere considered insulting nor impolite...
it' s a standard way to try to understand how to reply and the knowledge level of the TS
so to mimick You words... is not good to assume that I was assuming
my answer was not on the style search and go by Yourself...
and I took time to open the links to verify their accessibility
in order to post them for Your use
also when I post a about googling it means that I have
done the search with the string I suggested
and that the search has given enough results to be useful
it looks like You did not care to look at my signature
/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>
