>Thank you. This is even simpler than what they (VFPT) have in their solution. Interesting, however, that I see VFPT using PUBLIC variables whereas I understand (from your messages) it is not a good practice.

Some of the samples were written 15 years ago, before the good practices were established. I've often found the code there hard to follow, and believe me, I've been on a dozen projects and through code written by a few dozen people, I've seen a lot and found my way through it. This, and specially the code in accompanying apps (scx, frx converter, class browser etc) is in a class of its own.
