Use REF keyword


Link to this posting

Always add REF before actual parameters passed to a called method by reference.

In fact, this short keyword is playing the role of a comment:

Code: Select all
dw_main.GetChild("status", ref ldwc_status)

It really helps to understand scripts, especially when calling functions have multiple arguments in both the directions - "in" and "out". It was a bad solution of PB creators to make ref an optional keyword - let's make it required of our own free will!
