Re: Internally defined by key value?

This is part of a quite old (pre ILE era, converted) program that reads
a dual format logical file. The records are called REL2A and REL2B, the
READE finds both formats.  The keys are similar:

FCustomer  IF   E           K DISK                                      
FNomRel2   IF   E           K DISK                                      
FTabRelac  IF   E           K DISK
