[Coco] OS9 HEX to DECIMAL conversion.

[Wayne Campbell]

Curtis,

The $ operator, so far as I've ever been able to determine, does not
convert decimal to hex. What it does is tells Basic09 to treat the number
following it as a hexadecimal number. This means that $10 is stored in the
i-code as 0010, not 000A.
