New COBOL Compile Option: Global ON SIZE ERROR

When you want to handle overflow conditions and want to avoid truncated fields you have to code the ON SIZE ERROR statement for all computational statements.
This is tedious work.
In addition any decimal overflows conditions were suppressed by Language Environment for Cobol programs. So today you can only handle overflow conditions with ON SIZE ERROR.

We would like to have an option to detect decimal overflows, e.g. some sort of global ON SIZE ERROR clause.

With COBOL V5 new compiler options to detect nonconforming data formats were established (NUMCHECK). Depending on the sub-option set a messages is displayed or an abend is raised.

Like NUMCHECK this new option should raise a message or an abend in case of a decimal overflow depending on the sub-option (MSG, ABN) provided.
It should only apply to statements where no ON SIZE ERROR clause is provided by the developer.

    IBM Enterprise COBOL for z/OS is a continuous delivery offering, and aims to satisfy the needs of a rapidly evolving market segment. Product strategy evolves and requirements are continuously evaluated against that strategy. This RFE has recently been reappraised against the wider product strategy and does not fall into IBMs delivery plans for the next 12 month. Whilst this RFE might be valid and we might look to deliver longer term, this RFE is being rejected at this time. The requirement will be kept in our internal RFE backlog and might be reassessed in the future.

    This RFE is being accepted and is being moved to 'uncommitted Candidate'. It will be updated further once put into plan.

    The request could be implemented by exception handling as proposed in the Cobol ISO 2014 standard:

    - declarative:

    USE AFTER EXCEPTION CONDITION exception-name

    - compilation directive

    >>TURN exception-name CHECKING ON | OFF

    - exception name

    EC-SIZE-xxxxx

    Hi,

    We have discussed this internally and we believe if we were going to implement this, it would cause a runtime performance degradation. You can currently test the performance by adding ON SIZE ERROR.

    Please let us know if the performance degradation is acceptable if we were to implement this.

    Thanks.

    This RFE is still being evaluated and will be updated accordingly.
