I would use these two types primarily when external factors require it.
Some VB and Windows functions take Integers, not Longs, i.e. the VB graphic
functions.
Byte arrays are frequently used to process chunks of binary data, such as
bitmaps and OLE objects, where byte level access is needed.

IF you have a large array, say 100K or more, then it might make sense to use
shorter integer types. Even then, you can pack a long with several values,
writing some methods to get at the individual values. I have done this with 32
1-bit flags in a long, for instance, when each element of the array needed its
own set of flags.
