<P><FONT SIZE="5">3.9 Suppressing End of Line Markers</FONT><BR>
<P>End of line markers can be suppressed by the
<SAMP>@-</SAMP> sequence. A single occurrence of a
<SAMP>@-</SAMP> sequence serves to suppress only the end of
line marker following it and must appear <I>exactly</I>
before the end of line marker to be suppressed. No trailing
spaces, <SAMP>@!</SAMP> comments, or any other characters are
permitted between a <SAMP>@-</SAMP> sequence and the end of
line that it is supposed to suppress. The <SAMP>@-</SAMP>
sequence is useful for constructing long output lines
without them having to appear in the input. It can also be
used in the same way as the <SAMP>@+</SAMP> was used in the
previous section to assist in exposing the structure of
output text without affecting the output text itself.
Finally, it is invaluable for suppressing the EOL after the
opening macro text <SAMP>@{</SAMP> construct. For example:
<P>
<PRE>
@$@<Walrus@>@{@-
I am the walrus!@}
</PRE>
<P>is equivalent to
<P>
<PRE>
@$@<Walrus@>@{I am the walrus!@}
</PRE>
<P>The comment construct (<SAMP>@!</SAMP>) can also be used
to suppress end of lines. However, the <SAMP>@-</SAMP>
construct should be preferred for this purpose as it makes
explicit the programmer's intent to suppress the end of
line.
