Error description
When "SET TO FALSE" clause used against negative numbers it gives a wrong output. Sample code : ============================================================ 05 VAR_A PIC S9. 88 VAR_A_OK VALUE ZERO WHEN SET TO FALSE IS -1. Results : The expected results should be -1 instead the result is 0. ============================================================
Local fix
Local Fix is to change VALUE ZERO to VALUE 0.
Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL V6.2 compiling and * * running programs that contain the newly * * added features of WHEN SET TO FALSE and SET * * xxx TO FALSE with a condition-name * * definition that has a figurative constant * * for the true value. * **************************************************************** * PROBLEM DESCRIPTION: After a SET CN TO FALSE statement the * * conditional variable CV1 has the true * * value and not the FALSE value if the * * condition-name is defined something * * like this: * * 05 CV1 PIC S9. * * 88 CN VALUE ZERO * * * * WHEN SET TO FALSE IS -1. * * and this SET is executed: * * SET CN TO FALSE * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * **************************************************************** The compiler was getting confused by the figurative constant since there were some bits that did not get reset for the WHEN FALSE phrase.
Problem conclusion
The compiler was changed to reset the bits for condition-names before the WHEN FALSE processing, and now the SET statement executes with correct results after recompile.
