SHL operator

Syntax:

variable = value SHL increment

value value to be shifted

increment number of shift increments

Function:

Bits are shifted to the left using the function SHL. You can specify both the value to

be shifted and the number of shift increments directly or via a variable.

If the limit of the data format is reached, the bits are shifted beyond the limit without

displaying an error message.
