When calling procedures, passing by value means that the actual data (i.e. 10 bytes in your case) is pushed onto the stack. When calling by reference (including Const parms) a pointer (16 bytes) is pushed on the stack.

Thanks, Jon. That makes sense, and it hammers home the point.

So, I did a little digging into whether XMLSERVICE supports
pass-by-value at all, and it does. But boy, it's ugly to actually use
it:

https://bitbucket.org/inext/xmlservice-rpg/src/master/test.byval/

As if the "standard" call syntax wasn't bad enough! I don't really
have words for the by-value call syntax. Well, not polite ones,
anyway.
