I have been trying to use a button on my Stream Deck to modify ATC ID in MSFS 2024 without success.

I have been testing in the Script Editor with a simple script

A35·(>A:ATC·ID,·String)

The Script Editor does not like any non numeric characters being sent to the variable so the indicator is red but the Debug Window shows the script executing but there is no change to ATC ID.

In an attempt to validate what I am trying to achieve I ran SimVar Watcher from the SDK and was able to change the ATC ID. On a side note SimVar Watcher did not accept non numeric characters either but I was able to modify the program to allow me to paste in non numeric characters.

String literals must be enclosed in single quotes
'A35'·(>A:ATC·ID,·String)

Spec is here:
AAO manual -> "RPN Operators in AAO" -> "String operators" -> first line after that header.

Thanks, I thought that I must have made at least one silly mistake!

The addition of single quotes does turn the light green but there is still no change to the value of ATC ID.

You're right, it doesn't. Strange, that used to work.

Must be a bug of some kind, I will look into it.

Confirmed, that is a bug. Assigning values to String AVars is not possible at the moment, even the work around method fails.

Sorry about that, the issue will be fixed in the next version.

Thanks for looking into the problem.
