Once apon a time along time ago I was introduced to a technique called hi-nibble/lo-nibble. Back then I was a pascal newbie trying hard to pass GCSEs.

The principle was simple useing (128 I think) and some maths function one could take the first two parts of a string and store them in one byte. High and low!!

The problem is now that I have a usefull function for this fella I can't remember it.

If anyone has any idea what I am on about please help.
