Well, you have access to shell functions with PipeRead, and there's
FvwmPerl, but apart form that I think SetEnv is the only option.

All (conditions) xxx
will loop through all windows, you can add an assignment for each window
that matches.

There are variables such as $[w.id], $[w.width], etc that if accessed in
the context of a window are expanded to that property.

I'm not aware of any, some commands need to run in the context of a
window, but can be prefixed with Pick, Current, WindowId, etc. I think
most commands will use the Pick mechanism if they need to be run in the
context of a window but are'nt?

yes, see #3.18 in the faq.

How about this:
AddToFunc SavePosition I All (CurrentPage) SetEnv Position-$[w.id] "\(True\) AnimatedMove $[w.x]p $[w.y]p"
AddToFunc RestorePosition I All (CurrentPage) PipeRead "echo Test \\$\\[Position-$[w.id]\\]"
Uses a PipeRead though :) You could use FvwmEvent to UnsetEnv variables
as windows are destroyed...
I'm not sure if this needs the new Test syntax in cvs or not.
