Field Name <Stable> Use In Regular Expressions S’abonner

Hello,

I'm using Bartender Version 10.1 SR4 build 2961
I've created a User-Defined Protocol:

Request Stable Weight Command : ?

Request Stable Weight Pattern     : (?:(?<Status>(?<Stable>S)|U))(?<Weight>\d)\x23

Screen Picture: [attachment=1761:User-Defined Protocol.png]

I use a software to response to the Com Port.

Now, I send to Com Port : S8#

And Test window shows: [attachment=1762:Test.png]

As you see, It catches 8Kg weight, but why Bartender doesn't receive <Stability Flag>

Unfortunately, there is no example how to use stablility flag expressions in Bartender.

Please help me understand <Status> and <Stable> variables.
