Missing functions in COBOL

To determine the size of an array, most programmers use a constant and check the index against the constant. As an alternative compiler option SSRANGE can be used, which is not very performant.
It might be a good choice to have functions which return the size and/or the dimension of an arry

    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.

    An array is not necessarily full, and usually it is not.
    A function returning the maximum number of elements of an array will not be used often. What is important is to know the number of elements actually loaded in the table and this cannot be determined at compile time but by the logic of the program.
    For variable size array (bounded or unbounded), the DEPENDING ON clause is associated with a variable containing the size (maximum number of elements, not number of loaded elements) of the array.
    For fixed size array, the size can be computed by "LENGTH OF array / LENGTH OF element" (also true for variable size array).
