positive number ^ positive number
positive number ^ zero or a negative number
zero or negative number ^ positive number
zero or negative number ^ zero or negative number = 0
Example:
VAR1=5 ^ -1
Result:
VAR1=1
For a bitwise exclusive OR (using
exclusive ORed with the corresponding bit of the value on the right side of the operator. Each bit
comparison will be composed of 9 possible combinations:
1 ^ 1 = 0
1 ^ 0 = 1
0 ^ 1 = 1
0 ^ 0 = 0
Example:
VARB1=b0000 1111 XXX1 ^ b10XX 10XX 10XX
Response to VARB1 is *VARB1=10XX_01XX_XXXX_XXXX_XXXX_XXXX_XXXX_XXXX
Example:
VARB1=h32FD ^ h6A
Response to VARB1 is *VARB1=1010_0001_1111_1011_0000_0000_0000_0000
Example:
VARB1=h7FFF ^ b1101 1111 0000 1101
Response to VARB1 is *VARB1=0011_0000_1111_0010_XXXX_XXXX_XXXX_XXXX
