50-minute request: What does the RECCOUNT () command in computer VF mean?

Reccount ([nWorkArea | ctablealias]) returns the numerical parameter nworkarea to specify the number of the workspace where the table is located. RECCOUNT () returns 0 if there are no open tables in the specified workspace. CTableAlias specifies the table alias.

If disk space()>(gnFileSize * 3) Wait window "There is enough disk space for sorting." The Otherwise Waiting Window is out of disk space. The sorting could not be completed. ENDIF
