Q&A
Q Can I declare more than one variable in a declaration statement?
A Yes. However, keep in mind that nonspecific comma-delimited variables will be Variant types.
Q Can I declare constants in one place and use them in more than one place?
A Yes. Constants are declared at the top of the module, just as Global variables _are. Effectively, a constant declared outside of a function or subroutine is _Global. These are the safest kind of Global variables because their values are unchangeable.
Q Can I experiment with different implementations of the same solution without writing different functions and subroutines?
A Yes. This is one possible use for the Immediate window.
