USFile.EOF

note

This article is about the EOF method of the USFile internal component.

USFile.EOF

Checks if an end-of-file is reached when reading a file. May be used in conjunction with the ReadLine method to check if all lines have been read.

Returns 0 when the end of the file has not yet been reached, and 1 if it has been reached.

Syntax

INVOKE     USFile.EOF WITH
SELECT     *alias*

The required and case-insensitive alias is the alias of the file to be closed. This alias must previously have been assigned to a file at the time when the USFile.Open method was called. Alias is a regular name string that may or may not use the 'USFile.' prefix.

Example

SELECT  USFile.ReadLine( 'USFile.ToursFile ')
WHERE   USFile.EOF( 'USFile.ToursFile' ) = 0
