[WD20] - HFILTER() Issue

Hi All

I have such a simple problem;

I have a file. It contains many records but 2 records I am interested in. The only difference in the 2 records is a boolean field; one record is set to true, the other record has the field set to false.

I set a HFILTER() condition on the file for the boolean field = True.

I then do a HREADSEEKFIRST() for a record I am looking for. The seek condition is NOT the boolean field, it is on another field. And it still finds the record whose boolean field does not match the HFILTER().

Help says that HFILTER() applies to HREADSEEKFIRST() and so should work. No error occurs when applying the HFILTER().

Why does this not work?

TIA
