No. They are actually two different types of colons. One tells the text
drawing routine to go to the next line prior to printing it though. Both
colons use one byte and it does not matter which you use.

The regular colon is so that you can run several commands from the
homescreen. If I have several very short lines, I will write them across
to jsut keep the code neat and organized.

The best way is to press [ON] [F5] [ENTER] as soon as you make the
mistake.

Well, if you want to do it that way, have a menu that asks if they want to
continue or change what they entered.
