The EOF Function indicates that the end of a file has been reached.


Syntax

DO WHILE NOT EOF(filenumber&)


  • Filenumber is the number of the file being read. # is not required.
  • Returns 0 until the end of a file. This avoids a file read error.
  • Returns -1 (True) at the end of the file.
  • CHR$(26) can be used to denote the end of a file.
  • Note that GET can return invalid data at end of file. Read EOF after a GET to see if end has been reached and discard last read.
