Function

Checks the end of the sequential file, or whether or not the communication buffer
becomes empty.

Format

EOF ( <file number> )

Term

<file number>:

The number assigned to the file by the OPEN statement

Explanation

The EOF function returns -1 (true) when the specified file reaches EOF (End of File).

If the specified file does not reach EOF, the EOF function returns 0 (false).

A sequential file and RS-232C communication file are available.

When the EOF function results in -1 in the RS-232C communication file, it means the
buffer is empty.
