Word names in RETRO generally follow the following conventions.
<br/><br/>
<br/><br/>
&bull; Readability is important<br/>
&bull; Be consistent<br/>
&bull; Don't use a sigil as the first character of a name<br/>
&bull; Don't use underscores in word names<br/>
&bull; Use short names for indices<br/>
&bull; Word names start with a <span class="tt">-</span> for "not"<br/>
&bull; Words returning a flag end in ?<br/>
<br/><br/>
<br/><br/>
The word names will generally follow a form like:
<br/><br/>
<tt class='indentedcode'>[namespace:]name</tt>
<br/><br/>
The <span class="tt">namespace:</span> is optional, but recommended for consistency
with the rest of the system and to make it easier to identify
related words.
<br/><br/>
<span class="h2">Case</span>
<br/><br/>
Word names are lowercase, with a dash (-) for compound names.
<br/><br/>
<tt class='indentedcode'>hello</tt>
<tt class='indentedcode'>drop-pair</tt>
<tt class='indentedcode'>s:for-each</tt>
<br/><br/>
Variables use TitleCase, with no dash between compound names.
<br/><br/>
<tt class='indentedcode'>Base</tt>
<tt class='indentedcode'>Heap</tt>
<tt class='indentedcode'>StringBuffers</tt>
<br/><br/>
Constants are UPPERCASE, with a dash (-) for compound names.
<br/><br/>
<tt class='indentedcode'>TRUE</tt>
<tt class='indentedcode'>FALSE</tt>
<tt class='indentedcode'>f:PI</tt>
<tt class='indentedcode'>MAX-STRING-LENGTH</tt>
<br/><br/>
<span class="h2">Namespaces</span>
<br/><br/>
Words are grouped into broad namespaces by attaching a short
prefix string to the start of a name.
<br/><br/>
The common namespaces are:
<br/><br/>
<tt class='indentedcode'>|&nbsp;Prefix&nbsp;&nbsp;|&nbsp;Contains&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;|</tt>

<br/><br/>
<span class="h2">Tips</span>
<br/><br/>
<br/><br/>
Avoid using a sigil as the first character of a word name. RETRO
will look for sigils first, this will prevent direct use of
the work in question.
<br/><br/>
To find a list of sigil characters, do:
<br/><br/>
<tt class='indentedcode'>'sigil:&nbsp;d:words-with</tt>
<br/><br/>
<br/><br/>
Underscores in strings are replaced by spaces. This is problematic,
especially with variables. Consider:
<br/><br/>
<tt class='indentedcode'>'test_name&nbsp;var</tt>
<tt class='indentedcode'>#188&nbsp;!test_name</tt>
<br/><br/>
In this, the string for the name is converted to "test name". The
store in the second line will not add the space, so resolves to an
incorrect address.
<br/><br/>
I personally recommend avoiding the use of underscores in any word
names.
