Re: Couple more newbie questions.

Rob - serious thought here for once - does John really NEED to learn 
DDS? At least for tables and all? Might he not actually be able to go 
the SQL route? He may already know Query Management, which is part of 
mainframes, I believe. Those would give him formatted printed output 
without printer files. And there is the CICS product - that'd give him 
screens.

Or they might go completely to web-based interfaces.

Modernize? Eh? What say?

OK - back to my corner
