Lread() uses the Fopen() function to open a spreadsheet file. If Fopen()
fails, then an empty array will be returned.  Examine the value of FERROR()
immediately after the call to Lread().  The error returned from Ferror()
will indicate what caused the problem.  The most likely DOS errors you will
run into are:

Ferror()  Meaning

   2     File not found, check your spelling
   3     Path not found, check your path name and network rights
   4     Too many files open, so increase your file handles
  15     Invalid drive specified, check you file's drive letter
  21     Drive not ready, so close the drive door
