Basic Operational Statements
The following operational statements can be used in the program.
Item
substitution
addition
subtraction
multiplication
division
residue
OR
AND
NOT
Exclusive
Complement of 1
Bit Shift (left)
Bit Shift (right)
Reference
If executing logical operation, process must be performed between the same data types
(between word, bit, or long access)
E.g.$SW0L=$SW10L&$W20L;'Use all long access of word'
Multiple operations can be combined.
E.g. A=(B+C)*(D+E/2)

Example
A = B Substitute B for A
C = A+B Set A+B to C
C = A–B Set A–B to C
C = A*B Set AxB to C
C = A/B Set A/B to C
C = A%B Set A%B to C
C = A|B Logically ORs for A and B
C = A & B Logically ANDs for A and B
C = !A Set C for denial of A
C = A^B Result C of logical XORs for A and B
B = ~A Set the 1-complement of A to B
C = A<<B Set the value that A is ltic shifted B-
bit to the left to C.
C = A>>B Se the value that A is arithmetic
shifted B-bit to the right to C.
