Closed as program error.
Error description
The APARs PH21007 (v6.3 January 2020 PTF) PH20362 (v6.2 February 2020 PTF) PH22131 (v6.1 February 2020 PTF) made a change to simplify migration when using ZONEDATA(NOPFD|MIG), but has the incorrect effect on MOVEs of copying the sign of the signed zoned data source item to the unsigned zoned data item target.
Local fix
The problem is bypassed using ZONEDATA(PFD), but raise issues elsewhere if the program in dependent on ZONEDATA(NOPFD|MIG).
Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL 6.3 compiling and * * running programs compiled with the * * ZONEDATA(NOPFD|MIG) option, where the * * programs contain a MOVE or COMPUTE * * statement that moves a zoned decimal sender * * to a zoned decimal receiver and either the * * sender or the receiver is signed, but not * * both. * **************************************************************** * PROBLEM DESCRIPTION: Incorrect result. * * * * The high nibble of the last byte of * * the receiver may be set incorrectly to * * the high nibble of the last byte of * * the sender. * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * **************************************************************** To achieve better compatibility with V42 during zoned decimal to zoned decimal moves when the sender contains invalid data, a change was made to avoid fixing up the sign nibble of the receiver in certain cases, but the condition under which the sign fixup was avoided was applied too broadly.
Problem conclusion
The compiler was updated so that V42 compatibility is improved for zoned decimal to zoned decimal moves when the sender contains bad data, but this new behavior is now done under the correct conditions.
