I have been trying to learn and write some VBA procedures in Excel on my
hope Excel version (XP). I wish to use these on my office version (2000).
They are quite simple but the 2000 acts strange in several ways that it
should not, based on what I keep reading in books and the help file.

First, I do not have to declare each and every variable on the XP version.
If they are not declared with a DIM statement then they are established as a
variant on first use. This matches what I read in all the books and the
help file in both versions.

Second, I try to create a carriage return in a message box by using
&Chr(13). It works fine on the XP version but the 200 version says,"
Compile Error: Cannot find project or library."

What am I missing here? Is there a setting in the 2000 versions that I
should alter?
