A string like that can only produce characters stored in the Coco ROM or 
video chip. It would be different if you were running a graphics program 
that displayed characters internal to the program. Then you could 
display almost anything.

If you can find some CHR$ string that prints -> as a single character 
instead of a minus sign - and then the > sign, please post it. That was 
the request of the OP.
