RE: subject: SQL Vs. RPG Opinions -- MIDRANGE-L

Also, from the REXX reference:

"Note:  To use the EXECSQL environment on a system that does not have the 
DB2/400 Query Management and SQL Development Kit Version 2 LPP, 5763-ST1, 
installed, see the DB2 for AS/400 SQL Programming for special instructions for 
handling the REXX program."

That's from the section on ADDRESS with EXECSQL. It hasn't been updated in 
ages, but seems to hold true into OS/400 version 5. There appears to be zero 
documentation beyond the notes in the REXX Reference; DB2 manuals don't mention 
it, AFAIK. A call to IBM a number of months ago led nowhere except "It's seems 
to work on our systems."

And it works here.

The power of REXX combined with the power of SQL allows lots of interesting 
stuff.
