Special note from the editor:

To be filed in the "everybody makes mistakes column."

During my testing of the TestBox program, I didn't notice that I had Range
Checking turned off. As a result, the program ran fine. Unfortunately,
it shouldn't have. If I had had range checking turned on, TP would have
told me (quite rightfully) that I had a range check error when I initialized
the mouse.


I'VE ALREADY CORRECTED THE PROGRAMS IN THIS ARC FILE.


But if you're curious what I changed, I

#1)

changed the data type used in the MOUSE.PAS unit from Integer to Word
This makes the variables match the Register and related variable types.

#2)

changed the definition of two variables in the routine
DialogBoxObj.GetResponse of the GRPHBOX.PAS unit from

Mx,My : Integer; {Mouse press locations (x,y)}

to

Mx,My : Word; {Mouse press locations (x,y)}


Hopefully, since you're downloading the listings, you haven't spent
any time trying to puzzle through this. If you have spent time, my apologies.
