Enterprise Cobol V6 - No use of ED and EDMK HLASM instruction when OPTIMIZE level is not 0

We found that the Enterprise Cobol V6 did not use the ED and EDMK assembly instructions for formatting the edited numeric fields when the optimization level was not at 0 : OPTIMIZE(1|2).
We deduced that these ED and EDMK instructions had an impact on runtime performance.

Could this point be detailed in the "performance tuning guide" ?

    Hi, the performance tuning guide is to aid customers on how to tune their COBOL programs, rather than documenting which assembly instructions the compiler generates.

    However, please do open a performance PMR if for your program gets better performance with V4.2 at NOOPT than V6 at OPT(0).

    As a result, this RFE is being rejected.
