RPG does a great job of prefixing the fields.  Check out the PREFIX keyword.

Eric,

You're the man!

I will readily admit that I'm an SQL dummy. So I have to ask, how does
this translate into a creatable, maintainable source member?

For example, I have a field AccountNumber which is used in 14 different
physical files.  Each occurrence needs to have a different name to avoid
buffer to variable content conflict.  I.E. AccountNumber in master file
vs AccountNumber in transaction file.

Some languages, not RPG, will prefix the variable by the file name, but
we live in an RPG world.  So please educate me on how I can extrapolate
AccountNumber to 14 uses, uniquely named?
