exec command in specified region in empty window

[Dmitry Bolshakov]

hi

is it possible to setup shell alias so that an output of the command would be 
in the specified screen region

-------------------------------------
|>                                  |
|>                                  |
|> alias myls='screen -X at ??? ls' |
|> myls /                           |
|>                                  |
-------------------------------------
|boot   etc     misc        tmp     |
|cdrom  fsrv01  mnt         usr     |
|data   home    opt         usr2    |
|dbs    initrd  proc        usr3    |
|dev    lib     root        var     |
-------------------------------------

more precisely is it possible without creating shell window? (i need not shell 
i want to run only specified command and look at the output)
