Description:

            SUBROUTINE PGQDT(N, TYPE, TLEN, DESCR, DLEN, INTER)
            INTEGER N
            CHARACTER*(*) TYPE, DESCR
            INTEGER TLEN, DLEN, INTER
      
       Return the name of the Nth available device type as a character
       string. The number of available types can be determined by calling
       PGQNDT. If the value of N supplied is outside the range from 1 to
       the number of available types, the routine returns DLEN=TLEN=0.
      
       Arguments:
        N      (input)  : the number of the device type (1..maximum).
        TYPE   (output) : receives the character device-type code of the
                          Nth device type. The argument supplied should be
                          large enough for at least 8 characters. The first
                          character in the string is a '/' character.
        TLEN   (output) : receives the number of characters in TYPE,
                          excluding trailing blanks.
        DESCR  (output) : receives a description of the device type. The
                          argument supplied should be large enough for at
                          least 64 characters.
        DLEN   (output) : receives the number of characters in DESCR,
                          excluding trailing blanks.
        INTER  (output) : receives 1 if the device type is an interactive
                          one, 0 otherwise.
