SHL operator
Bits are shifted to the left using the SHL (SHIFT LEFT) operator. 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.
