The overhead of producing numcheck IGZ0279W message is ridiculously high

In our experience, the overhead of checking for valid numeric values associated with the numcheck(xxx,msg) compiler option is tolerable. But if an invalid numeric value is found, the overhead of actually producing the IGZ0279W warning message is r...

Cobol V5 - Evolution for TEST option - TEST(EJPD,NODWARF) for non IBM debuging tools

Cobol V5 brings support of DWARF information for debugging programs. The TEST compiler option has evolved accordingly. Cobol V5 optimizer is much more "aggressive" in binary code that Cobol V4 optimizer. To trace the execution of a program, regard...

Cobol V5 - Program malfunctions if compiled with OPTIMIZE

With Cobol V4, we met dysfunctions with a program compiled with option OPTIMIZE(STD). This problem persists in Cobol V5 under certain conditions. The program is badly written but the use case was real. The problem:? a main program described a comm...

Cobol V5 - constant expression 2 ** 31 not resolved by optimizer at compile time

The compiler does not resolved the expression "2 ** 31" in a comparison statment or in a compute statment, and generated code do a call to IGZXPR2 runtime routine (this is expensive at runtime).

COBOL DB2 PROCESSOR deficiency

We believe the following issue is not an enhancement but rather a deficiency in the COBOL compiler's attempt to eventually replace the DB2 pre compiler. The COBOL compiler needs to fully mimic the behavior of the DB2 pre compiler as far as display...

Priovide a utility to format COBOL Signature Bytes out of a loadmodule or program object

If customers don't have a compiler listing avaiable, i.e. OEM software, they are not able to identify the signature bytes (like compile time options)

Cobol DYNAM subroutines - usage of DSNULI

Currently DB2's Universal Lanugage Interface (DSNULI) is useless for Option-DYNAM-compiled Cobol subroutines. Please make Cobol fully fit for DSNULI. Local situation: Many DB2-programs at our site are written in COBOL and are used in TSO/Batch, ar...

Compiler option to ignore NUMCHECK on editing char to suppress leading zeroes

Developers have a lot of code resulting in runtime errors. 2. For reports, generally we use the definition as ZZZ,999,999.99 and will try to move a value from the field which is defined as 9(9).99. This is to display first 3 zeros as spaces in a r...

Compiler option to ignore last nibble on ZD during comparison

Developers have a lot of legacy code which is resulting in run time errors with V6 due to redefining a field which has a sign bit with a field which wasn't defined with sign bit or defined as character. Solution Proposed: IBM need to make change t...

Provide an compile option detecting illegal data in COBOL5 in numeric variables

Arithmetic operations on PIC9 fields containing non-numeric values should lead to an ABEND or WARNING message, depending on user's choice through a compiler option to detect the illegal data and eventually a runtime option to differentiate between...
