Error description

  • S0C4-4B DBFCMP11 MOVESEG3 on 64-bit DEDB buffering system
    ( FPBP64 = Y ) and DEDB with segment compression.
    R0 is used in MOVESEG3 to reference 31-bit work area by MVCL
    in 64-bit mode, but R0 at entry to DBFCMP11 as x'00000001'
    and it is never cleared in DBFCMP11 before MOVESEG3 is called.
    It appears the caller, PL/X module DBFMCSS2, may have corrupted
    the register. It should be cleared before use in DBFCMP11.
