VAL
Return the numeric value of a number string
VAL(X$)
This function converts the string X$ into a number. It is the
inverse operation of STR$. The string is examined from the left
most character to the right, for as many characters as are in
recognizable number format. If the Commodore 128 finds illegal
characters, only the portion of the string up to that point is
converted. If no numeric characters are present, VAL returns a 0.
EXAMPLE:
10 A$ = “120”
20 B$ = “365”
30 PRINT VAL (A$) + VAL(BS)
RUN
485
XOR
Return exclusive OR
XOR (n1,n2)
This function provides the exclusive OR of the argument values
n1 and n2.
x = XOR (n1,n2)
where n1, n2, are 2 unsigned values (0-65535).
EXAMPLE:
PRINT XOR(128,64)
192
Note: n1 and n2 need not be whole numbers.
