>I have a character field zip c(5) containing zipcodes. I need to set a filter to select the bad entries which contain alpha characters. This is done in Access code using the LIKE function (not like('#####'), but VFP handles LIKE differently. This would also seem to be a simple matter but I can't seem to find the answer. I could find a bad entry by parsing the values but that doesn't serve my need to set a filter.

We found that this techniques does not prevent from input of bad Zip codes.
We got a 100K rows table with USA table with ZipCodes, Cityes and States, which reduce number of bad codes
