Thanks for your response.   

Actually, I have run with a RAMDRIVE under DOSEMU and  a typical
job runs about twice as fast.  If I redirect the output to 'nil', 
nothing much seems to change (except there is no screen output).  So it
looks like the int's and accompanying real/protected mode switching 
is the problem.  I'm still pursuing a solution.

	Regards,
