   I have a nice mthod for a spectacular crash of Gulam.prg (a version
posted to the net).  It is not that I want to brag about it, but you
may do it by a mistake nad have a nasty surprise.

WARNING!  Try it only on RAM drive or scratch floppy, since the only 
method of recovery will be to de-install RAM drive, or reformat your
disk!!!!

Try the following sequence of commands:

mkdir testd
mkdir testd\expmd
ls -l >testd\dirf   # this for better effect
cp testd\* testd\expmd

Now lean back and watch effects.   There is nothing, short of resetting
your computer, that you can do anyway.   (It will create a recursive
structure of subdirectories which you cannot remove, since rm command
does not have either -r or -f option.   GEM will also barf on you after
a short while, coming with nonsense error messages).
   I believe that this bug is closely related to 'rm *', mentioned by
John Turner.
