Name
       colcrt - filter nroff output for CRT previewing

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

Description
       The  command provides virtual half-line and reverse line feed sequences for terminals without such capability, and on which overstriking is
       destructive.  Half-line characters and underlining (changed to dashing `-') are placed on new lines in between the normal output lines.

Options
       -  Suppresses all underlining.  It is especially useful for previewing allboxed tables from

       -2 Causes half-lines to be printed, double spacing the output.  Normally, a minimal space output format is used which will  suppress  empty
	  lines.   The	program  never	suppresses  two  consecutive empty lines, however.  The -2 option is useful for sending output to the line
	  printer when the output contains superscripts and subscripts which would otherwise be invisible.

Examples
       A typical use of would be:
       tbl exum2.n | nroff -ms | colcrt - | more

Restrictions
       Can't back up more than 102 lines.

       General overstriking is lost; as a special case `|' overstruck with `-' or underline becomes `+'.

       Lines are trimmed to 132 characters.

NAME

       colcrt - Filters text processor output for screen previewing

SYNOPSIS

       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

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

DESCRIPTION

       The  colcrt command provides virtual half-linefeed and reverse linefeed sequences for terminals without such capability, and on which over-
       striking 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

       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

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