The HEX$(n) function converts a number n to a string in hexadecimal
notation.

To convert a hexadecimal-notation string (x$) back to a numeric value
from x$ = HEX$(n), use VAL("&H" + x$).

The OCT$(n) function converts a number n to a string in octal notation.

To convert a octal-notation string (x$) back to a numeric value from
x$ = OCT$(n), use VAL("&O" + x$).
