How do I check if a toolbar is open/closed (on/off) using @if,
tried @if:Toolbar "Main"=on
and @if:Toolbar "Main"=open

Simple commands can include some very limited conditional logic via @if and similar but we don't call it scripting (although it wouldn't be wrong to say it is a type of scripting, in the more general sense).
You already had the right syntax for @if:Toolbar NAME="xyz"
