TROFF(5)            UNIX Programmer's Manual             TROFF(5)

NAME
     troff output - format of output from troff(1)

DESCRIPTION
     The output is in the following octal numbers:
     000-077   normal characters
         100 initialize
         101 lower rail
         102 upper rail
         103 upper mag
         104 lower mag
         105 lower case
         106 upper case
         107 escape forward
         110 escape backward
         111 stop
         112 lead forward
         113 undefined
         114 lead backward
         115 undefined
         116 undefined
         117 undefined
     120-137 size change
     140-177 lead (140: lead 31;   177: lead 0)
     200-377 escape (200: esc 127;   377: esc 0)

     The following table shows the correspondence from octal
     _t_r_o_f_f code to ASCII characters as stored in _t_r_o_f_f fonts.
     The actual octal code obtained is only 6 bits long if it is
     a character and the case bit (0100) is added in software
     depending on the current case as defined above.
