[Coco] OS9 HEX to DECIMAL conversion.

[coco at jechar.ca]

So based on what you said I tryed

PROCEDURE add
PRAM as:STRING
PRAM bs:STRING
a=VAL(as)
b=VAL(bs)
print a+b
END

Still dosn't work what is the PRECISE syntax for PARAM
and when I call the routine will

basic09 add 5 8

be okay or do I need to call as

basic09 add "5" "8"
