I am interesting in using the opto-script function 'GenerateForwardCrc16OnString'
In 1701 document (and Help also) I see the next example of applying this function:
POSITION = GenerateForwardCrc16OnString(0, MSG_TO_SEND);
This is a function command; it returns the forward CRC. The returned value can be consumed by a variable (as shown) or by another item, such as a mathematical expression or a control structure.
Why return value is named POSITION? Is it really the offset in the string where the function places CRC been calculated?
