AREXX - get ScreenSize (solved: let the user set his/her screen res)

Hi devs ... and everyone interested

Is there a way (without using third party programs and/or
addons, like libs and stuff) to check (read in) the screen
resolution used on the machine the AREXX script is running?

Or, is there a way to read it out into a (ENV) var opening
up the possible use later?

I'm pondering over the question if i should add a feature to
one of my scripts, but am unsure if what i want to achive is
possible with AREXX.

err...and no, Python isn't an option due to me not knowing it

Thanks in advance
