Hi Scott.  Thanks for the info.

I was not aware that was possible.  If I set up the module to accept a
140 Alpha parm, non-CONST, passed by reference, I can get a pointer to
that parm, and build data structures based on that pointer?  Well, I
just answered my question by trying it...

I thought that if a parameter was passed by reference, because the
address was in the main module's pointer space, that you couldn't get
a pointer to it from a called module.  Where did I get that idea? 
This will make things much more efficient.  Thanks!

This is a set of several modules that analyze areas of the text report
line.  So each module defines a couple of data structures, to analyze
these different areas.  I wanted to simplify the main module, which
will simply be handing the report lines to the appropriate module, and
receiving back a data structure with a counter, and three output
record data structures, as each line can contain 0-3 accounts.
