Field naming was ( SQL is amazing)

Hi Rob

I never worked on S34.
Also I never did come up with a good solution for field naming. The 
biggest restriction being the 6 byte field size.
Program described field names were a proper dogs breakfast.

To get a comprehensive Field Where Used we used Pathfinder , dont know 
if it still exists.
Prior to Pathfinder I had a Field cross reference utility that used 
File/Field End position as the sort criteria.
Dug that info from Compile Cross reference listings,  wrote a utility to 
compile programs  into Qtemp then parsed the listing.
