    Hi.

    I'm currently working on some Arexx code.
    And by now I'm having ~500 lines. So far it's still OK. But there will be some more code.
    Basically much could be extracted into some sub modules.
    I'm not aware Arexx has a concept for including/loading other Arexx code.
    Or? Can this be done somehow?

    easily:
    Code:
    call submod1()

    will load submod1.rexx

    Hmm, yeah, that works, kind of.
    A script 'submod1.rexx' is loaded and executed upon call submod1().
    But when there is a internal function marked as PROCEDURE I'm getting an error: "Invalid PROCEDURE".
    Removing the "PROCEDURE" from the function doesn't produce an error but the function code is executed as well which is önot really wanted.
    Any advice?

    Indeed, an external procedure is not allowed. What do you mean by "executed as well"?
    > rx main
    FUNCTION 1 SUBMOD1 Work:Developing/submod1.rexx REXX REXX
    COMMAND 0 main Work:Developing/main.rexx REXX REXX

    Code:
    /* main.rexx */
    call submod1()
    call submod2()
    exit

    /* submod2 internal */
    submod2: procedure
    parse source s
    say s
    return

    Code:
    /* submod1.rexx */
    submod1: /*procedure*/
    parse source s
    say s
    return

    Ah, now I got it.
    In main, call submod1() loads a file submod1.rexx and executes any global operation plus it executes the first function it finds.
    However, other functions in submod1.rexx are not visible from main. Can you confirm that?

    Right, it's more like chain in BASIC, not linking in C.
