PH03581: INVALID SIGN DATA LEADS TO SIGN IN UNSIGNED FIELD AT OPT(1|2)

Obtain the fix for this APAR.

APAR status

• 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)

  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.
