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
