[Several generations of "how to detect MultiFinder" removed...]

Probably the best way, UNDER SYSTEM 6.0.x, to determine whether 
MultiFinder is present or not is to check to see if the System Heap and 
the "Application Heap" are contiguous.  That is, get the SysZone, add the 
ZoneLimit, and check to see if you wind up butting up against ApplZone.  
If you do ,MultiFinder ain't around.  If you don't, MultiFinder is around 
(under 6.0.x, some of MultiFinder's code winds up lying BETWEEN the System 
and Application heaps).

Hope this helps.
