Error 99                  Unexpected End of File                     pp 328


 Source:   IOResult

 Cause:    1)  Physical end of file was enountered prior to finding the
               EOF character (Ctrl-Z/1Ah) when reading from a text file.
           2)  An attempt was made to read beyond the end of file on a
               defined file.
           3)  A READ or BLOCKREAD is unable to read the next sector of a
               defined file.


 ----------------------------------------------------------------------------


 Remedy:   Examine the statement ahead of the error cursor for the above
           condition.

           Something may be wrong with the file itself, or BLOCKREAD might
           be attempting to read past the physical end of file.
