Example:
PRESS(VS1)
VAR01 = 16 SHL 2
VAR02 = VAR02 SHL VAR04
END_PRESS
SHR operator
Syntax:
variable = value SHL increment
value
increment
Function:
Bits are shifted to the right using the function SHR. 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.
Example:
PRESS(VS1)
VAR01 = 16 SHR 2
VAR02 = VAR02 SHR VAR04

The functions operate with radian measure. The functions SDEG() and SRAD()
can be used for conversion.
