Redisplaying a range of lines

The FLIP command lets you reverse the exclude status of a specified group of lines in a file or of all the lines in the file. This is useful when you have used the 'X ALL;FIND ALL xyz' command to find lines containing a string (xyz) and want to see the lines which do not contain the string. You can also use FLIP to show excluded note, message, and information lines.

You can enter one or two labels to specify the range of lines whose include status you want to reverse. If no labels are specified, the exclude status of all of the lines is reversed.

To reverse the exclude status of all the lines in a file, use this syntax:

FLIP

To reverse the exclude status of specified lines, use this syntax:

FLIP .a .b

The lines between labels .a and .b are redisplayed.
