You must add Nofilter or Readwrite if you want to create a "real" cursor, if you don't VFP will simply use the From table and set a filter to it. The way VFP behaves is very efficient, but it may cause serious problems when you want to use this cursor later. That's why they added the Nofilter clause which forces VFP to create a new cursor. Readwrite makes the new cursor updateable, and also makes the keyword Nofilter redundant.

From your code I guess that you simply want to check how many, if any at all, matches the criteria you specify, and in that case I suggest that you specify that the end result goes into an array. And as I wrote in another message, Reccount() will not always give you the correct number of records, use _tally insetad.
