Name typing
If you want to set a max of six, you could just do LEFT$(name$,6) I'm pretty sure. This would trim any extra characters.
If you want to be nice and re-ask them for their name...
@TOOLONG INPUT "Name?",name$ IF LEN(name$)>6 THEN @TOOLONGWhich will check IF the name was greater than six characters in length. It translates pretty well to code, actually.
