Title: Message
I am beginning to
encapsulate file access in a "Service Orirtented Architecuture" as described in
a previous post by Aaron Bartell. It is working very
well.
What is the
preferred method of providing a return code of the file operation to the calling
program ? Should I provide a return code on every procedure that I write ?
Or, just provide a
procedure to determine the status separately ? Like PartIsFound for
determining if a part is in the Item Master.
Also, I've seen
where others have standardized on always passing data back using the Procudure
interface and never parameters claiming that the parameters should only be used
for input to the procedure. If multiple fields need to be returned, a data
structure is used.
