RE: prob- reverse a string in cl * REXX is very interesting.

Tom,

You wrote:  REXX is very interesting.   Yep, it is.. and powerful.

As to your experiment with CL and REXX... as I mentioned, to me,
calling REXX from CL is about like using two programming languages when
the one with the greatest function is the tool to use.   While calling
REXX from CL can be done and is sometimes the best toolset to use, why
use CL when you can use REXX to do the same thing and more.    

And as your experiment showed, if you want to call REXX from CL or RPG
because REXX can do some operation simpler/easier or whatever, then use
the API; don't call the REXX processor each time.   But, as with any
tool, if used correctly and it the right place, it provides lots of
function and feature and makes the work easier.   

Usually, the biggest hurdle for AS/400 folks is getting over the
thought of substituting REXX for CLP as it's seen as blasphemy to use
anything except the standard CL and RPG.
