DESCRIPTION

AllocMem is a Shell command which temporarily allocates memory.

It's main purpose is to artificially decrease the amount of RAM available
without having to copy a large file to the RAM Disk.

POSSIBLE APPLICATIONS

ˇ Testing the behavior of programs under low memory conditions
ˇ Testing disk-based virtual (swap) memory
ˇ Simulating a ľA1 w/256MB RAM on an XE with 512MB+
ˇ Simulating a Classic Amiga w/128MB RAM on an A1
ˇ Wasting memory for no good reason ;-)

I did my best to make sure that it won't cause any crash, however the OS may
become unstable if you allocate most of the free memory, leaving less than a
few megs available. I could have added some safeguards against that but it
would prevent testing such a scenario so I deliberately chose to allow it.

The original motivation behind writing that command was that some bug in the
BrowserII copy function prevents it from working unless the amount of free RAM
is below 256MB, and I wanted an alternative to copying 100MB+ of data to RAM:
to make it work. 
Since then, Stephan Rupprecht wrote "AvailMemPatch" which took care of that
problem for all 68K apps. Thanks Stephan!
