Re: Load CL variables from SQL example -- MIDRANGE-L

On the other hand, REXX and SQL are indeed a wonderful match. You can use SQL within a REXX procedure and then call CL statements. REXX allows you to execute SQL statements (including fetch from a cursor in a loop) and then use the returned variables in CL statements.

I did an article about it way back when:

It's not as seamless as embedded SQLRPGLE, but once you understand the syntax it's extremely powerful.

While CL & SQL are not a match made in heaven, I've used the DCLF/RCVF technique in the past.

If you need multiple selects & files concurrently, keep in mind that CL will support up to 5 DCLF's.

If you're talking about a single record result, consider using a command calling an RPG to do the work. I write a lot of "RTV" type commands to return configuration info to my CL programs.
