The line immediately following this dot
command is used as a one-time overlay.
This means that the defined overlay line is
printed before the next regular file line,
with the regular file line printed on top of
the overlay line.
This feature is also useful in situations
where you want to issue a printer control
character (defined in a PAGE.CTL file)
without causing an extraneous blank line.
Example:
.OL
C
If the C above were a in a file, the .OL
immediately above it would cause the control
string for to be sent, followed by a
carriage return only, instead of the normal
carriage return and line feed.
