Allow qualified values within Dim( ) keyword in ILE RPG

In moving towards more modular development, we're attempting to move our program set up values to a data structure however the DIM keyword doesn't allow qualified variable names.

Use Case:

Define a data structure:
SetupEntries Ds Inz Qualified
MaxEntries 5S 0 Inz( 40 )

OutColumns Ds Dim( SetupEntries.MaxEntries )

    RPG does not allow any variable name to be coded in the DIM keyword. The parameter for DIM must be a constant.

    If the purpose for using a qualified subfield is to allow the dimension of the array to be changed at runtime, there is another RFE related to that: You can your vote to that RFE, and add a comment about your specific needs related.

    However, if your goal is just to set the dimension of the array according to the initialization value of the subfield, then define a named constant and use it for both the DIM keyword and the data structure subfield.


    SetupEntries Ds Inz Qualified
    MaxEntries 5S 0 Inz( MAX_ENTRIES )

    OutColumns Ds Dim( MAX_ENTRIES )
