I think I've found a bug in Replace Field Contents where there's a difference between a Button that runs a script vs. a button that has a single script step. I'd like another pair of eyes on it. The goal is to take the current found set, and make a list of the record serial numbers, using this cal…

Great observation. I think it is correct behavior since the scope of your $L local var is within the script (which clears out when the script terminates) in one case and in the other within the layout of the button since the single step button "script step" is not a script. Hope I explained well ..

BTW you could fix it and make it work as desired in the button by adding another case/if to your let statement: Let ( $L = if ( get ( RecordNumber ) = 1 ; Table::ID ; List ( ... ) ; ... )

I think you are correct, but it's even weirder. The $L variable is not only persistent on the layout, it also keeps its value on other layouts and TOs as well. So the real issue appears to be something more general: a local $Variable set in a Button that executes a Single Step, the $Variable wil…

since it isn't properly documented at least AFAIK it might get out of control to grasp entire behavior in every foreseeable contexts and it might slightly alter its behavior on revised versions.

This is old news. $variables are designed to be scoped to a script. Their behaviour outside of scripts is undocumented, poorly understood and discouraged.

Where I am with @xochi is that a one script step button appears to some as a mini script and therefor somehow expected behavior to be consistent..
