RE: Date compare Best Practices

I actually did give a presentation to a controllers meeting here years ago 
on how the advances of RPG affect them.  They understood it and wanted 
their stuff changed, quickly.

RE: Date compare Best Practices






It's going to take a few more jobs moving west past Hawaii, I'm afraid.

Some managers believe what they don't know, nobody else should know.  And 
there are plenty of departments out there with limited knowledge, and even 

less understanding, of the forces driving their business.  Without a 
business perspective, their voices are ignored, and too many programmings 
think /and act/ like the business exists to keep the IT department busy. 
Without a business perspective, there are few opportunities for the IT 
department to propose new projects requiring new thinking and new 
technology.

I wonder how many IT departments have given their executives a 20-minute 
presentation on how the advances in RPG benefit the company, even if the 
benefit isn't immediately obvious?

This is a knowledge business, and you can't stop your learning just 
because 
the little hand points to the "5".  If you're not advancing, you're 
falling 
behind.  It's a mindset...people say, gee, I don't like triggers when they 

should be peppering their peers with intelligent questions to learn "why".

It's not about technical skills any more...it's about attitude.
