Used to perform a logical conjunction on two Boolean expressions, or a bitwise conjunction on two integer values.
result
=expression1*BitAndexpression2Parts
- result
-
Required. Any Boolean or numeric expression. For Boolean comparisons, the result is the logical conjunction of two expressions. For bitwise operations, the result is a numeric value resulting from the bitwise conjunction of two numeric expressions.
- expression1
-
Required. Any Boolean or numeric expression.
- expression2
-
Required. Any Boolean or numeric expression.
Remarks
For Boolean comparison, if both expression1 or expression2 evaluate to True, result is True. If expression1 evaluates to True, and expression2 evaluates to False the result is False. If expression1 evaluates to False, and expression2 evaluates to True, the result is False. The following table illustrates how result is determined:
| If expression1 is | And expression2 is | Then result is |
|---|---|---|
| True | True | True |
| True | False | False |
| False | True | False |
| False | False | False |
For bitwise operations, the *bitAnd operator performs a bitwise comparison of identically positioned bits in two numeric expressions and sets the corresponding bit in result according to the following table:
| If bit in expression1 is | And bit in expression2 is | Then result is |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
Note Since the logical/bitwise operators have a lower precedence than other arithmetic and relational operators, any bitwise operations should be enclosed in parentheses to ensure accurate execution.
If the operands consist of one Boolean expression and one numeric expression, the result Boolean expression will be converted to a numeric value (-1 For True, and 0 For False) and the bitwise operation will result.
Example
dclconst Hex24 Value( H'24' )
dclfld Byte1 Type( *byte ) INZ( H'46')
dclfld Byte2 Type( *byte )
dclfld Int1 Type( *integer2 ) INZ( H'46' )
dclfld Int2 Type( *integer2 )
dclfld Bool1 Type( *Boolean ) INZ( *true )
dclfld Bool2 Type( *Boolean )
dclfld Str2 Type( *string )
Byte2 = Byte1 *BitAnd Hex24 // Byte2 = H'04'
Int2 = Int1 *BitAnd Hex24 // Int2 = 4 or H'0004'
Bool2 = Int2 *BitAnd H'11' // Bool2 = False
Str2 = Int1 *BitAnd Hex24 // Str2 = "4"
Int2 = Bool1 *BitAnd H'0C00' // Int2 = 4 or H'0004"
