Re: SQL in CL.

Vern, Scott,
Thanks a lot for your suggestions. I appreciate it. Scott, you are
absolutely right...it does make sense to post the right question in the
right forum. I just did not know about the midrange-l. I will make sure I do
that from here onwards. Now, back to the topic of discussion...hmmmm....so
there is no way of embedding SQL in a CL program?

This is my situation...I have a few(about 6 to 8) CL programs which take the
user input via a DSPF and process those parm's against the dB files and
enable the user an option to print the reports. The CL programs look
something like the one that I already posted.

I am trying to modify these CL programs so that when ever a user feeds in a
parm through the .dspf I would take that parm and give it to a SQL statement
in the CL program and then do the report processing...

I appreciate all your suggestions. Thanks for the input.

Jake.
