RE: opendir() in RPG IV

        Jon, with due deference there are a few things here I disagree
with. 

        > C functions on the other hand _only_ support passing by value.
        Nope. In fact strings are passed by reference by default.
        > When calling a C function you should always use the VALUE
keyword.
        There's no reason to do this unless you want to protect your
original values or you're passing constants from an EVAL statement.  
        > Simple answer is _always_ pass by value then you can't get
into trouble.
        The overhead in passing large strings into frequently used
routines should alone give you reason not to do this.

        I do agree that the VALUE/CONST usage is more than a tad
confusing (in practice rather than just in theory). I'll swear that I've
got RPG routines that do similar things where VALUE will work in one and
CONST in the other.
