Error Codes

   An error code indicates whether the last operation succeeded or
   failed, and if it failed, the reason.  There are three groups of
   error codes: general errors, protocol file transfer errors, and DOS
   errors.

   [5.0] In the Clipper 5.0 version of Telepathy, these error code names
   are defined in the header file telepath.ch.
