BIT.OR - Use logical OR with Bits
Use logical OR with Bits
Intention
OR returns TRUE (non-zero) if any of the Bits in P1 AND P2 are "1".
Therefore OR will make sure that the given bits are set to 1.
The parameters P1 and P2 can be given as value or as "binary".
You can choose whether P3 will be "as value" or "as binary". If you do not specify whether "b" or "v" the result will take the format of P1.
Using P4 you can decide how many Bytes the result should have, 8, 16 or 32 bit.

Syntax
BIT.OR|[b/v]P1|[b/v]P2[|[b/v]P3][|P4]
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 - 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 P2.
P3 - optional,Variable for result. You can define with a prefix of "v" for value and "b" for "binary" the format of the result. If the prefix is omitted the result will have the format of P1.
If the P3 is "-" then result is placed on the TOS.
P4 - 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.
