[AccessD] Integer v. Long

[Stuart McLachlan]

Nope. It's a matter of efficiency.

In a 32bit or 64bit operationg system (Access and WIndows) the OS uses 32 bit  registers to 
manipulate integral values. Every time you use a 16 bit integer, the OS has to handle the 
translation to from 32bit.

Bottom line - Longs are more efficient, especially for things like large loops.
