Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Post your ideas

  1. Post an idea.

  2. Get feedback from the IBM team and other customers to refine your idea.

  3. Follow the idea through the IBM Ideas process.

"automatic" calculation of the length of a data-item

We need that the length of a data-item can be calculated automatically in relation to its context: this data-item is used in REDEFINES of different length, and must correspond to the REDEFINES which has the greatest length.

This way of doing things is imposed by our proprietary CICS communication middleware.

Today these structures are produced by a code generator that we will have to abandon (it is no longer maintained by its editor).
Tomorrow we will have to code these structures ourselves.

We would like to have a feature that dynamically computes the length of a variable relative to its context, as is possible in IBM assembly language by the "L" attribute.

    Structure are not pad to blank for use of statement "move length of structure to…".

    Requirement for length at start of structure is required by middleware (API) : transport of messages based on length of message (cics statements : writeq ts, send, etc.)

    In the provided example, the implicit redefinition could be replaced with explicit redefinition, or use the MSG-LENGTH field as the controlling entity. It is not clear from the example the best way to re-write it, but we would be happy to work with you to help you.

    We would not be inclined to introduce a change in COBOL based on the needs of a proprietary CICS communication middle ware and obsolete code generator. Hence, this RFE is being rejected.

    To re-write the provided example, we would need to know why the message cannot be padded with blanks, and where the length of message requirement comes from.

    Thanks.

    This RFE is still under consideration
