Declare variables and call procedures directly on the declare

Today if we want to call a procedure that has a return value, we have to declare the variable, data structure etc and then call the procedure like this:

dcl-s eligiblefreight packed( 11 : 3 );

eligiblefreight = rlsitm_getEligibleFreight( batch );

It would be extremely helpful (and simular syntax like other languages)

if we could directly declare the variable and call the procedure like this

dcl-s eligiblefreight = rlsitm_getEligibleFreight( batch );

It would also be extremely helpful if you can declare the variable anywhere in the procedure. (middle of the logic, beginning of the logic etc. )

for example

if ( batch > 0 );

dcl-s eligiblefreight = rlsitm_getEligibleFreight( batch );

if ( eligiblefreight > 0 );

// do something

    IBM does not intend to provide a solution to this Idea at this time, so it is being closed.

    It is not feasible to change the RPG compiler to support complex initializations such as calling a procedure.

    However, the additional aspect mentioned in the description is more feasible. If you want this additional aspect to be considered, please open another Idea requesting "block-scoped variables", where you could define a new variable to be used within a structured section of code such as an IF-block. Such a variable could not be used outside the block it is declared in.

    I'm not sure if I like this suggestion.
    But OK - let's follow the suggestion.

    The syntax should then be something like:

    dcl-s eligiblefreight likePR( rlsitm_getEligibleFreight );


    dcl-s eligiblefreight likePI( rlsitm_getEligibleFreight );

    Thus it is possible to see where the definition comes from.
