Left Shift operator

Shifts the bits within the left operand by the amount specified in the right operand. The bit on the left disappears and a 0 is shifted in on the right.

If the left bit is a 1 an overflow will occur, and an error message is displayed. To prevent this, use the bitwise AND (&) operator in an expression.

For example,

(dev << 1) & 65535

where 65535 is

1111 1111 1111 1111

in binary form, and where

dev

is a tag name, whose value is being shifted left.
