Syntax
FEOF(<expN>)

Description
The FEOF() returns a logical true (.T.) if the file pointer is at the end of the specified ASCII file. The ASCII file is specified by its file handle <expN>. The file handle should be assigned to a memory variable when the file is opened with the FCREATE() or FOPEN() functions.
Example
use accounts fp=fopen("existing.file") if fp > 0 do while not feof(fp) ? fgets(fp) enddo endif
