[Function] Converts the hexadecimal data in the column in Operand 2 to a binary number and assigns this to the variable in
Operand 1.
The length set by the SLEN command will be converted. Only the integers will be converted and the decimal
places will be disregarded.
[Example] SCPY 10 ' 1234'
SLEN 4
VAL 1 10
Set ' 1234' in column 10.

The hexadecimal number ' 1234' in column 10 is converted to the binary number 4660 and assigned
to variable 1.
LET 1 100
LET 2 20
SCPY 20 ' ABCD'
SLEN 4
VALH *1 *2
Assign 100 to variable 1.
