Using Symbols and Expressions
in Report Generation
Chapter 8
8Ć14
If user symbol B’s bit pattern contains:
1001001100000000
The 1775-S4B scanner would return the following for the expression:
0110110011111111
Report generation supports the following bitwise operators:
& or .BAND.—bitwise 32-bit AND
^ or .BXOR.—bitwise 32-bit EXCLUSIVE OR
| or .BOR.—bitwise 32-bit OR
Bitwise operators enable you to manipulate 32-bit values. For example:
If you enter:
G=(Q.BAND.T)
G stores a 32-bit result of the binary AND operation between user symbols
Q and T. You can also use.BXOR. and.BOR. operators to perform binary
EXCLUSIVE OR and binary OR operations.
Report generation supports the following logical operators:
.AND.—logical AND
.OR.—logical OR
Logical operations return 1 if the expression is true and 0 if the expression
is false. For example:
If you enter:
A=10
B=9
C=3
D=4
P (A.GT.B .AND. C.NE.D)
The 1775-S4B scanner prints out a 1 in this case because 10 is greater than
9 and 3 is not equal to 4.
