[comp.sys.intel] Looping with 386 ecx register

ray@ole.UUCP (Ray Berry) (07/01/89)

	All of the (3rd party) 386-asm documentation I've looked at states
that ECX is used when looping on the 386.  I.e., counts greater than 2^16
are allowed.  When I execute this instruction (on a pc), the top half of
ecx is ignored.  Is this a function of the cpu operating mode?  Can some-
one shed a little light on this?  Thanks in advance...
