Re: externally defined data structure + renamed fields = confusion!!! !!

Hi Dave,

i think PREFIX should do the trick. I thought i could find an example 
easily, but i was wrong. If my brain is still working, it should work like 
this:

FFile1     IF   E                DISK
FFile2     IF   E                DISK          PREFIX(C)

DFile1DS     E DS                          EXTNAME(File2)
DFile2DS     E DS                          EXTNAME(File2)  PREFIX(C)

Then the field is called CF0001, but that shouldn't matter much, does it?

(the above snippet is untested and uncompiled and may contain errors; but 
you should get the idea.).

best regards,

Anton Gombkötö
