RE: Invoking a program which is not in the existing application.

Rowthu,

If what you really want is a way to validate fields before writing them to a 
file thencan you consider writing a trigger program?

I am presuming that at some point these fields will be written to a file.  You 
could write a trigger program against the file itself, and if a field's values 
are not correct, then pop up a correction process including valid values and 
instructions.  This may not be elegant but it meets your requirement to not 
touch the original programs.

I've used this a few times and it does work, but if the original program writes 
a report based on the wrong values then your report won't match the file's 
data.  Still, it is an option to look at.
