Hello,
The code in READ ME was example that just DISPLAYS GROUP ID in the COMMENTARY window.
"GroupID : " + Stock.GroupID();
statement means concatenate string containing "GroupID : " to the result of Stock.GroupID().
Resulting is a STRING "GroupID: 5" that will be displayed in COMMENTARY window.
Commentary window works so that it automatically displays statements that evaluate to strings
in its output window.
This of course DOES NOT assign any value to GroupID variable because there is
NO GroupID variable. "GroupID : " is a STRING CONSTANT (literal), not variable.
If you wrote this
GroupID = Stock.GroupID();
(NOTE NO QUOTES !) then it will be variable, and assignment operator (=) can assign it.
Best regards,
Tomasz Janeczko
