This would be my first choice.

Don't even need that commitment. I have no problem with the compiler issuing
an error if it finds a variable declaration or procedure name that conflicts
with any current, or future "reserved" name. Even for existing applications,
it is not that big a deal to change a procedure name if you need to.

This would be my second choice - if you REALLY have to do it that way.

Yuck! This is the absolute worst. My fingers are getting sore just thinking
about all the additional typing.

Not another alternative.. just another request... any way to drop the "CF"
as well?


BTW, thanks for allowing us to have some input into the decisions.
