OR
Gets the logical sum of two expressions.
Format
<expression1> OR <expression2>
Parameter
Return value
Returns the logical sum as an integer value.
Description
Gets the logical sum by bit of the expression specified in the <expression1> parameter and the expression
specified in the <expression2> parameter.
When the values of the <expression1> parameter and <expression2> parameter are double precision real
values, the decimal part is rounded off.
This can also be used as an Or condition in an If statement. For details on the logical expression, refer to
"Operators".
Reference: XOperator (p.213)
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If a value outside the range -2147483648 to 2147483647 is specified as an integer parameter, an "Overflow"
error will occur.
If a value is assigned to the return value variable or the variable is not used in an expression, a "Syntax error"
error will occur.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
Usage Cautions
• None.
Example
Gets the logical sum of 1 assigned to the variable EXP1& and 4 assigned to the variable EXP2&.
The result is shown below.
