RE: Sharing variables between procedures

These procedures are all in the same module.  I thought about making the
data structures global, but I really want each of the four "main" procedures
to have independent copies of the data.  I could, of course, define four
global data structures with the PREFIX keyword, but I think the
EXPORT/IMPORT approach is more elegant.  It has the added benefit of showing
the relationship between the "main" and "child" procedures. 

I hadn't thought about using pointers for this, but I probably should have.
I am using them to handle a multi-occurrence data structure in another
module.  

Thanks.

Don, are the procedures in the same or different modules?  If they are
in the same module, you can specify the data structure once at the
beginning of the module outside of any procedures, and it will be
"global" to all the procedures in the module.

If they are in different modules, you can simply pass the data structure
between them, but that involves copying a lot of data.

Another way to pass data structures between procedures is to use a
pointer:
