Notes:      - The file format  must be set to  'POST', 'PSCL' or
              'PDF' with the routine METAFL.
            - Font names cannot be shortened. Some printers pro-
              vide additional  non-standard fonts.  These  fonts
              should  be specified  exactly in  upper  and lower
              characters  as they are described  in the  printer
              manuals.  PostScript  suppresses  any graphics  if
              there is a syntax error in the font name. Standard
              font names are not case-sensitive.
            - A call to a DISLIN font resets PostScript fonts.

              and must  contain  the first five fields of an X11
              font. DISLIN adds then the point size and a trans-
              formation matrix to the font.  IF COPT has not the
              value 'STANDARD', it must begin with the character
              '-'  and contain the last 6 fields of an X11 font.

CALPH         is a character string  containing an alphabet.  In
              addition  to the  names in  BASALF, CALPH can have
              the value 'INSTRUCTION'.
 C1           is a character that shifts to the alternate alpha-
              bet.
 C2           is a character that shifts back to the base alpha-
              bet.  C1 and C2  may be identical.  After the last
              plotted character  of a character  string,  DISLIN
              automatically shifts back to the base alphabet.

              'GERMAN',  the characters  A, O, U, a, o, u  and s
              placed directly after C will be plotted as Ae, Oe,
              Ue, ae, oe, ue and ss.  With CNAT = 'DANISH',  the
              characters A, O, E, a, o  and e will be plotted as
              A-ring, O-slash, AE, a-ring, o-slash and ae.
Notes:      - Shift characters can be defined multiple where the
              characters must be different.

              fonts and by COMPLX.   
Name: MIXALF  3
Indices and exponents can be plotted by using control characters
in characters strings.  The routine  MIXALF instructs  DISLIN to

        [     is used for exponents. The character height is re-
              duced by the scaling factor  FEXP  and the  pen is
              moved up  FBAS * NH  plot coordinates  where NH is
              the current character height.
        ]     is used for indices. The pen is moved down  FBAS *
              NH  plot coordinates  and  the character height is
              reduced by the scaling factor FEXP.
        $     is used  to move  the pen  back  to the base-line.
              This will  automatically  be done  at the end of a
              character string.

FBAS and FEXP have the default values 0.6 and 0.8, respectively,
these values can be changed with the routines SETBAS and SETEXP.
