Your software vendor may be referring to the problems I discussed in my 6.5
Communicator article, "Compatibility Considerations for COBOL and C."  In a
nutshell, if you compile code on 6.5 and then try to link it or add it to an
XL on 6.0, you could have problems.  The COBOL II/iX compiler on 6.5 was
updated to make use of new millicode routines for more efficient 64-bit
arithmetic, and those routines aren't present in the millicode library on
6.0.

But that shouldn't cause a problem when moving forward.  I don't know of any
scenario where COBOL code compiled on 6.0 can't be brought forward and mixed
with code compiled on 6.5.
