DR>   How do can I read the individual bits that are inside a byte?
     Using Boolean Algebra, usually the AND Operator is
what you want.  See F1 Help.
     Suppose you want to know if the sixth bit is on.
IF a AND 32 THEN
If true, it is; if false, it isn't.  Decimal 32 is
binary 00100000.  If that sixth bit is also on in your
variable "a", then the statement will be true.
   a = 00101010
   AND 00100000
result 00100000  therefore sixth bit is on.
   a = 01001010
   AND 00100000
result 00000000  therefore sixth bit is off.
