COBOL Compile option 'NUMCHECK(MSG)' function improvement request

We applied the COBOL Compile option 'NUMCHECK(ZON,MSG)' to prevent 'invalid data' that may occur during program execution.
As a result of testing, we found that there were a lot of programs with 'invalid data' code.
Program developers have the following difficulties in using NUMCHECK.
To solve this, we request functional improvement.

1. Even though it is defined as NUMCHECK(ZON,MSG), a warning message + ABEND 4038 occurs during execution and the CICS Transaction is terminated.
The customer's request is to show only a warning message in MSG option and not to generate ABEND as described in the COBOL manual.
That is, the program is executed like NONUMCHECK, and the developer wants to debug through the additionally provided warning message.

COBOL 6.3 Programming Guide..
> If MSG is in effect, a runtime warning message with the line number, data item name, data item content, and program name is issued.
> If ABD is in effect, a terminating message is issued that causes an abend.

2. If there are several 'invalid data' codes in one program, ABEND occurs in the first one. Therefore, many iterative tests are required to debug the remaining problems.
The customer's request is that the NUMCHECK (MSG) option provides a warning message for all 'invalid data' codes in the program at once.

    This item is being tracked via Case TS006801251 and is currently not an RFE. Hence, canceling this RFE.

    Hi,

    The NUMCHECK(MSG) option must not trigger an abend at the CICS level. With us it works (the messages appear in the CEEMSG output of the CICS).
    The abend can be caused after the NUMCHECK message, if you have not enabled an option to automatically correct numeric data: NUMCHECK only tests, but does not correct the values. It is NUMPROC or other options that make the necessary corrections.

    I suggest also that you examine the language environment option TERMDHACT set at your CICS.
    To do this, use the CLER transaction.
    Depending on the option chosen, this may hide the origin of the U4038 / U4039 abends.
    We use UAONLY to have dump on language environment runtime errors.
