The break control word (.br) interrupts the display of text on a line, and continues it on the next line. The break control word must be the only entry on the line. For example, assume the source file has the following lines.

:p.These words
appear on
the same line.
.br
These words
.br
do not.

The output looks like this:

These words appear on the same line.
These words
do not.

If you enter text on the same line as the break control word, the IPF compiler ignores the break control word.
