The test ran significantly FASTER on a 233mhz Win 98 wkst with 64m of ram (VFP 5.0) than on a 4.5mhz II NT 4.0 WkSt with a 128m of ram using VFP 6.0. Also as I stated originally it ran even faster on a 233mhz NT 4.0 Server with 128m using VFP 6.0 than it did on the Win 98. But that is understandable -more ram and a SCSI drive. If I chase it down, I'll get back to you.

HAVING is used to filter the result set rather than filtering the source tables.
