Eof() --> lRet

Checks whether navigation reached the end boundary.

EofAdvPL

01 · OVERVIEW

Overview

Eof returns a logical flag for the current alias. DBGoBottom positions on the last record but does not set EOF; moving past it can. An empty table already has true EOF. The example qualifies owned test table EDTRB, already open without pending changes, and only reports current state. EOF is not a record count, and fields must not be read when it is true. (TOTVS, n.d., ref. 1)

02 · SYNTAX

Syntax

Eof() --> lRet

Return value

Logical: true at the end boundary or on an empty table.

    EndIf
Return Nil
