[Coco] DEF USR and strings?

[Allen Huffman]

Cool. The Extended Color BASIC manual even showed how to return a string:

A$=(USR1(VARPTR(A$))

You can have your ML subroutine modify B$'s value and then end the routine with an RT$ instruction. This causes U$R to return with B$’s modified value.

Weird use of extra parens, though.
