 Below is an adb session that will allow you to change the amount of
 per process memory allowable.  This patch works for Xenix versions
 2.x as well as 3.x on the Tandy version of the kernel.

 Note on the 3.1 Tandy kernel the per process size is already set to
 512k per user process, so this patch is not needed.  I guess The Small
 Computer Co. finally bugged them enough :-)

 One additional note, you need the development system to apply this
 patch since you need 'adb' which is distributed with that product.

 (at your prompt (the '%' below is a typical C-Shell prompt) you would type):

   % cp /xenix /xenix.256k
   % adb -w /xenix
   _Maxmem?D
   	(to display current allocation)
   _Maxmem?W	512
   	(to set allocation to 512k per user process. [NOTE: You should have
   	available at least 1 meg of swap per user on your system! Also note
   	that you could use a number greater than 512 however keep in mind
   	how much memory you are dealing with, the most you can possibly
   	have is 1 meg. It is not recommeded that you go higher than 512k
   	unless you are the only user on the system and you don't mind alot
   	of large process swapping. (lots of overhead!!!)])
   $q
   	(to quit adb)
   	(you must now re-boot Xenix to have the patch take effect.)
