DBGoBottom
DBGoBottom() --> NilMoves to the last logical record.
Overview
DBGoBottom moves to the last record under the active order and filter, not necessarily the corresponding physical position. It returns Nil; check EOF before reading fields. The demonstration changes its owned alias position and only reports whether an accessible record exists. EDTRB identifies only an owned test table already open with the required schema and permissions; examples are not intended for standard tables. (TOTVS, n.d., ref. 1)
Syntax
DBGoBottom() --> NilReturn value
Nil; not a logical success indicator.
