***       SETCHT - SET CHARACTER TYPE.
*
*         SET CHARACTER TYPE ALLOWS A TASK TO CHANGE THE CHARACTER
*         TYPE ASSOCIATED WITH A PARTICULAR TERMINAL.  THE ARGUMENTS
*         ARE CHECKED FOR VALIDITY AND A *CTI* CALL IS MADE IN ORDER
*         TO PASS THE REQUEST ON TO THE NETWORK SUPERVISOR.
*
*         CALL FORMAT -
*         FORTRAN EXTENDED - CALL SETCHT(TERMINAL,STATUS,ACT)
*
*         COBOL - ENTER SETCHT USING TERMINAL, STATUS, ACT.
*
*                 TERMINAL = TERMINAL WHICH IS TO HAVE ITS ATTRIBUTES
*                            CHANGED.  TERMINAL IS 1 - 7 CHARACTERS,
*                            ZERO OR BLANK FILLED.  IF A BINARY ZERO
*                            IS SUPPLIED, THE OPERATION APPLIES TO
*                            ORIGINATING TERMINAL.
*
*                 STATUS = LOCATION WHICH IS TO HAVE THE TERMINAL
*                          LOGGIN STATUS RETURNED.
*
*                 ACT = INTEGER VALUE FOR FORTRAN AND COMP-1 FOR
*                       COBOL, VALUE RANGING FROM 2 - 4, OR THE
*                       CHARACTER STRINGS - *ASCII7*, *ASCII5* AND
*                       *DISPLAY*.
