You're right, backticks won't work there, you do need to
use PipeRead.
For example:
PipeRead 'echo echo value $(($[w.width]-10)).'
produces:
[FVWM][Echo]: value 756.
the first echo is for the shell, the second one for Fvwm.
The $(()) is to get the shell to evaluate the arithmetic.
This was done in FvwmTalk which had a width of 766.
I'd construct and test the Resize command, but I don't
want to spoil the fun.
