Jojo,

There's no good reason for doing that.

It's easy to put some external procedure/prgs that can be called on the command click event to process a certain job. The App is done this way, calling sub program from a command button under VFP 6..

Yes, we all know that its easier to debug a program or app written with a lot of forms, class and prgs., but for this app's case, one form is enough to process a job which is to produced reports and and text files for Accounting purposes..
