  • Closed as program error.

Error description

  • A USAGE DISPLAY data item, such as A PIC S9(x)V9(y), is
    redefined as B PIC S9(x) and C PIC V9(y). Then a value is moved
    to B, and then eventually A is moved to D, where D has as many
    digits as B and is unsigned (e.g. PIC 9(x) or PIC ZZZZ9 when x
    = 5).  The value of D may contain the byte corresponding to the
    sign code in B.
    

Local fix

  • Compile with OPT(0)

    *                      B will still contain a sign code.       *

    ****************************************************************
    The compiler was assuming that all zone bits were x'F' (except
    for situations the compiler was already aware of, when
    ZONEDATA(NOPFD|MIG) were used). Thus, the compiler didn't
    generate code to correct the invalid data and set the sign of
    the final receiver to x'F'.
    

Problem conclusion

  • The compiler was fixed to set the sign of the final receiver to
    x'F' in the case described above, provided ZONEDATA(NOPFD|MIG)
    is specified.
