MFPLI10110W STATIC INITIAL of RECSIZE allowed at compile-time, but dynamically changing RECSIZE at OPEN is not supported.

The record size of a file is established at compile-time and changes to the RECSIZE variable will not change the file record size at OPEN time.
Resolution:
Remove dependency on changing the record size of the file dynamically.
Module:
DCLREE.PL1, PASS1.PL1
