 eof()
 Determine logical end of file
------------------------------------------------------------------------------
 Prototype

     ERRCODE eof(
                  WORKAREAP wa,
                  BOOLP isEof
                )

 Arguments

     wa is a pointer to self.

     isEof determines the logical end of file.

 Description

     Indicates whether the current cursor for wa is at the logical end of
     file.  This method provides the return value of the CA-Clipper EOF()
     function.

 Default Behavior

     Copies wa->eof to isEof.

 Implementation Notes

     .  Determine wa->eof status, then call SUPEREOF().

     .  If your RDD supports relations, update relations with a
        forceRel() prior to determining wa->eof status.

     Warning!  isEof must point to one byte of allocated memory.
