RE: Sharing variables between procedures

Import and Export is supported only with GLOBAL variables.
That is fields or data structures that are NOT defined within a
subprocedure.
You declare a variable (field or data structure) that you would like to
share between separately compiled *MODULEs, and then add the EXPORT keyword
to it. Then in the *MOUDLE objects in which you would like to use that
EXPORTed variable, you declare an identical variable; in both name and
attributes; and add the IMPORT keyword to it.

Subject: RE: Sharing variables between procedures

Okay, so it appears from the manual that I need to define the data
structures with different names in my four "main" procedures (File1DS,
File2DS, File3DS, and File4DS).  I then use IMPORT in the "child" procedures
.  That would make the File1DS values available only to the File1DS "main"
procedure and its "children".

Do I understand this correctly? 

Thanks again.
