I come from the Fox2.x world and have only recently begun work with VFP. The problem with NOFILTER came up here Monday and it took me 30 minutes to track down what was happening (which incidently, the help file on SELECT-SQL was what pointed me to NOFILTER). I noticed a few things during my investigation and was hoping people could enlighten me on the way NOFILTER works and SELECT's workings in VFP now (is there any other difference I should be aware of).

Things I noticed:
1) The filtered cursor only seemed to be created when the where clause had an indexed element and you were selecting all, eg:
Select * from Table Where LogicalFld into Cursor Temp

2) You could still use that filtered cursor in append commands, eg:
Select Temp
lcDBF = DBF()
Select Table2
Append from &lcDBF

Thanks for the help.
