It certainly helped me. I can only think of one comment.

The choice of VALUE, CONST or reference can be greatly influenced by whomever 
wrote the procedure or program being called. When you write both calling and 
called procedure or program, you can set about any convention you want as long 
as you maintain your own consistency (and you don't try forcing violations of 
the rules such as what's allowed for extpgm() vs. extproc()). But when you 
call, for example, a system API that _expects_ the parameter to be passed by 
value, then you better code VALUE.
