Timer Functions

[Rolf Brandt]

I just needed to update an older program with some functionality to change timer intervals during runtime. Since PowerBasic does not have any special functions for it I wrote one.

Maybe it is helpful for someone else. There is also a little demo project attached to demonstrate the use of it.

I added also Timerfunctions.zip. It contains a folder which you can place in FF3's codestore so that you have the functions on hand with F8.
