You would only need to use PipeRead here to perform some mathematics, not to check if the window is overlapped (see the Overlapped condition), but potentially how much it is [1] overlapped by. Then, in the same statement, just call whichever function you choose with the correct number of arguments -- which FVWM will pass in, as $0, $1, $2, etc. So for example, if you had this: DestroyFunc Foo AddToFunc Foo + I Echo $0 + I SomethingWith $1 ... and you need to calculate what $1 needed to be beforehand: PipeRead `echo Foo hello $(($[SOME_ENV_VAR] + 23 - 1))` FVWM would execute "Foo" as expanding: $0 == hello $1 == whatever the result from the calculation was. Yes, I am contriving this deliberately -- so you'll have to fill in the gaps with the appropriate FVWM functions and values, etc. If you have problems then, with a specific function, you'll find the "EchoFuncDefinition" command useful. -- Thomas Adam [1] By this point, all of this becomes trivial using FvwmPerl, to be honest. -- "It was the cruelest game I've ever played and it's played inside my head." -- "Hush The Warmth", Gorky's Zygotic Mynci.
