In that case, would I still gain efficiency by changing 
>From this:
D VT100FormatScreenData...                 
D                 pr            80    dim(24)
D  piRecvData                32766    varying


To This?:
D VT100FormatScreenData...                 
D                 pr            
D  piRecvData                32766    varying
D  piScreen                     80    dim(24)  options(*nopass)

If the program uses the piScreen param to pass value back, it would
still have to copy the data from the global screen variable in the
procedure to the piScreen field.  That is no different from using the
return value where it has to copy data to the variable in the caller. 
Is there?

- Note:  I like to create procedure that return the value of what it
does.  It makes the caller program a bit more readable.  However, I also
understand that it makes the procedure become not as flexible since a
procedure can only return one value.

Does a return value return a pointer to a static variable?  No.  It
copies the entire contents of the variable from the subprocedure to it's
caller. 
That's why it's inefficient, and why I wouldn't do things that way.
