Re: [C400-L] calling a program using a variable

Thanks Alan,
Unfortunately REXX won't work in this case (performance and
tricky parameter passing).

Glen

Glen,

I don't know REXX at all, but I believe it is really good
at defning
variables on the fly and complex character string
manipulations. Not much
help, but maybe there's a direction to take it. Someone on
the midrange-L
list might help with that, there are some who are good at
REXX.
