CHAPTER 4

CATC Scripting Language for USB Operators

Bitwise Logical Operators

~ Bitwise

complement

Integer-integer Integer ~0b11111110 = 0b00000001

& Bitwise AND Integer-integer Integer 0b11111110 & 0b01010101 =

0b01010100

^ Bitwise

exclusive OR

Integer-integer Integer 0b11111110 ^ 0b01010101 =

0b10101011

| Bitwise

inclusive OR

Integer-integer Integer 0b11111110 | 0b01010101 =

0b11111111

Shift Operators

<< Left shift Integer-integer Integer 0b11111110 << 3 = 0b11110000

>> Right shift Integer-integer Integer 0b11111110 >> 1 = 0b01111111

Assignment Operators

= Assignment Any Any A=1

B=C=A

+= Addition

assignment

Integer-integer Integer x =1

x +=1=2

String-string String a = "one "

a += "two" = "one two"

Raw byte-raw byte Raw z = '001122'

z += '334455' = '001122334455'

List-list List x = [1, 2]

x += [3, 4] = [1, 2, 3, 4]

Integer-list List y =1

y += [2, 3] = [1, 2, 3]

Integer-string String a = "number = "

a += 2 = "number = 2"

*Note: integer-string concatenation uses decimal

conversion.

String-list List s = "one"

s + ["two"] = ["one", "two"]

-= Subtraction

assignment

Integer-integer Integer y =3

y –=1=2

*= Multiplication

assignment

Integer-integer Integer x =3

x *=1=3

/= Division

assignment

Integer-integer Integer s =3

s /=1=3

%= Modulus

assignment

Integer-integer Integer y =3

y %=1=0

>>= Right shift

assignment

Integer-integer Integer b = 0b11111110

b >>= 1 = 0b01111111

<<= Left shift

assignment

Integer-integer Integer a = 0b11111110

a <<= 3 = 0b11111110000
