Not to mention the fact that you _cannot_ specify anything _but_ a 'file'
as the source of the data to be handled. Want to read it from a mag tape?
Can't do it. Want to read directly from a serial port? =Can't= do it.
Want to read directly from the keyboard? *Can't* do it. Want to get the
input directly from another program, _without_ using an intermediate file?
CANT' do it. The GUI "open" dialog doesn't allow for that kind of flexibility.
In a pure GUI environment, if there =isn't= an _existing_ button/menu-item/
selection-list action for it, you _cannot_ do the operation.
This is, not incidentally, why _pure_ GUI environments have gone the way of
the dodo bird, except for some fixed-scope production uses.
EVERYBODY _today_ realizes a GUI _alone_ is 'inadequate' for 'general purpose'
use, and proivdes -- at a mnimum, an escape to a command-line, where you can
do 'anything'. e.g. the MS Windows "run" item on the start menu.
