colcrt

colcrt(1)						      General Commands Manual							 colcrt(1)

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.
