GEM can do word processing, DTP, spread sheets, draw vector graphics and
do some basic web browsing. GEM can also execute DOS applications from
inside GEM (so that you'll return to GEM when the DOS application exits).
It can also play MP3s (although some versions of GEMP3 don't seem to like
running on plain DOS).
There are some limitations to GEM.
- It uses the first 640kb of memory, so it can run out of memory if you
execute large applications (especially DTP or DOS applications from inside
GEM)
This can be 'cured' by using DJGPP - obviously, this'll require a 386 or
greater, but you then have the full system's memory available to you.
- It is a single-tasking enviroment
Unless you use GEM/XM, of course. :-)
- It is not LFN aware
It can be made LFN-aware though, as Kristaps says, if there's an LFN driver
loaded (eg, LFNDOS or DOSLFN or whichever way round it is, or Windows).
GEMP3, for example, can make use of long filenames if it's passed them, as
the DJGPP runtime automatically makes use of an LFN driver if one is loaded.
Note that the GEM file selector doesn't, of course, as it's not been
programmed to.
