BIT.NOT - Use logical NOT with Bits
Invert Bits
Intention
NOT generally inverts bit, it makes a 0 to a 1 and makes a 1 to a 0.
The parameters P1 can be given as value or as "binary".
The result is in P2 which is the invers of P1.

Syntax
BIT.NOT|[b/v]P1|[b/v]P2[|P3]
Parameter Explanation
P1 - Variable containing a value or binary number. For example take the Number "9". It can be an ASC-Code "9" or the numeric number "9".
You can define this with a prefix of "v" for value and "b" for "binary". If the prefix is omitted, "v" is the default setting for P1.
P2 - P2 - Variable for result or"-". If P2 is not a variable, the result is placed on the TOS.
You can define this with a prefix of "v" for value and "b" for "binary". If the prefix is omitted, "v" is the default setting for P2.
Also here you can specify [b/v] for the format of the result. If you do not specify anything the result is "value"-Format.
P3 - optional, can be 1,2 or 4. Number of Bytes that are used internally. The number of Bits is the number of Bytes times 8.
1 - 8 Bits
2 - 16 Bits
4 - 32 Bits
Do not use the "8" Option. See Limitations below.

Remarks
-
Limitations:
When using the "|8" Parameter, the lower 4 bits are possibly wrong. This is not a bug its due to the way variables are stored internally.
Therefore we recommend to not use this option.
