109
<P>FunnelWeb provides a <STRONG>quick name</STRONG> syntax
110
as an alternative, for macros whose name consists of a
111
single character, to the angle bracket syntax usually used
112
(e.g. <SAMP>@<Sloth@></SAMP>). A quick name sequence
113
consists of <SAMP>@#</SAMP>x where x, the name
114
of the macro, can be any printable character except space.
117
quick_name = "@#" non_space_printable
120
<P>The result is identical to the equivalent ordinary name
121
syntax, but is shorter. For example, <SAMP>@#X</SAMP> is
122
equivalent to <SAMP>@<X@></SAMP>. This shorter way of
123
writing one-character macro names is more convenient where a
124
macro must be used very often. For example, the macro calls
125
in the following fragment of an Ada program are a little
130
@! Define @<D@> as "" to turn on debug code
131
@! and "--" to turn it off.
133
@<D@>assert(b>3);
134
@<D@>if x>7 then write("error") end if
137
<P>The calls can be shortened using the alternative syntax.
140
@! Define @#| as "" to turn on debug code
141
@! and "--" to turn it off.
144
@#|if x>7 then write("error") end if
