FVWM: Calculation in config file

Hi there,

Is there a way doing some simple calculation in fvwm config file?

I am using FvwmButtons on top and FvwmTaskBar on bottom of the screen. I
have got two functions to maximize/resize windows. One is for showing
taskbar the other is for showing FvwmButtons and the taskbar:

AddToFunc ResizeToShowTaskBar I Maximize 100 -27p
+ I Raise

AddToFunc ResizeToShowButtons I Resize 100 773p
+ I Move 0 73p
+ I Raise

Since a working under different operating systems with different screen
resolutions it would be nice to use the functions above with variables
instead of 'hard' values:

AddToFunc ResizeToShowTaskBar I Maximize 100 -$[TASKBAR_HEIGHT]p
+ I Raise

AddToFunc ResizeToShowButtons I Resize 100 $[SPACE_BETWEEN]p
+ I Move 0 $[BUTTONBAR_HEIGHT]p
+ I Raise

I would like to set/calculate the environment variables in the init
section depending on the actual screen resolution:

AddToFunc InitFunction
+ I SetEnv TASKBAR_HEIGHT 27
+ I SetEnv BUTTONBAR_HEIGHT 73
+ I SetEnv SPACE_BETWEEN `$[vp.height] - $[TASKBAR_HEIGHT] -
$[BUTTONBAR_HEIGHT]`

I know the last line is not possible, but maybe someone got an idea to
obtain a similar behaviour.

Thanks in advance,

Uwe
