NAME    [Toc]    [Back]

       colcrt - Filters text processor output for screen previewing

SYNOPSIS    [Toc]    [Back]

       colcrt [- -2] [file...]

       The colcrt command filters  output  from  text  processors
       such as nroff so that it can be previewed on a cathode ray
       tube (CRT).

OPTIONS    [Toc]    [Back]

       Suppresses underlining;  this  is  useful  for  previewing
       boxed  tables  from  tbl.   Causes  all  half-lines  to be
       printed, effectively doublespacing the  output.   This  is
       useful  when  printing  output  with subscripts and superscripts
 on a line printer, where half-lines  do  not  normally
 appear.

DESCRIPTION    [Toc]    [Back]

       The  colcrt  command  provides  virtual  half-linefeed and
       reverse linefeed  sequences  for  terminals  without  such
       capability,  and on which overstriking is destructive. The
       colcrt command changes underline characters to dashes  and
       places  them  and  half-line  characters  on  new lines in
       between the normal output lines.

NOTES    [Toc]    [Back]

       colcrt cannot back up more than 102 lines.  General  overstriking
  is  lost;  as  a special case a | (vertical bar)
       overstruck with a - (dash) or _ (underline)  becomes  a  +
       (plus sign).  Lines are trimmed to 132 bytes.

EXAMPLES    [Toc]    [Back]

       The  following  command  line illustrates a typical use of
       colcrt: tbl exum2.n | nroff -ms | colcrt - | more
