Notes:	DVSIXDI is part of the DVSI (DESQview System Information) package by
	  Daniel J. Bodoh
	for v1.00, function 0003h allocates common memory, which the caller
	  must deallocate after reading the process information; only the
	  currently used records are placed in the buffer
	for v1.10+, function 0003h merely returns a pointer to the internal
	  array of process information; the caller should make a copy of the
	  array while inside a critical section (see INT 15/AX=101Bh).	Only
	  those records with bit 7 of the first byte set are valid.

Bitfields for DVSIXDI process flags:
Bit(s)	Description	(Table 03103)
 7	valid record
 6	(v2.00+) record is allocated; if bit 7 clear, process is "(starting)"
	  and only offsets 01h and 09h are valid
 5	(v2.00+) this app currently owns the CPU(Central Processing Unit) The microprocessor which executes programs on your computer.
 4	reserved (0)
 3	DESQview system task
 2	reserved (0)
 1	task has keyboard (currently unused)
 0	task swapped out (currently unused)
