This template provides a speedy way to wrap template source code in <code><nowiki>...</nowiki></code> markup. To work correctly, it must be substituted.
Recommended use is:
{{subst:codenowiki |1=(code)}}
i.e. so that anything before an equals (=) sign in the code isn't intepreted as a parameter name.
If the template is transcluded rather than substituted on a page, its output can be corrected by re-saving the page, triggering the substitution embedded within it:
To indicate text is a variable name. Use for any variable names except those including "I" (uppercase i) and/or "l" (lowercase L); for these, {{varserif}} should be used to ensure a noticeable distinction.
To display parameters as used in code (i.e. with triple braces), especially to indicate relationships between them. May be combined with {{para}} above.
() To indicate deprecated source code in template documentation, articles on HTML specs, etc. The {{dc2}} variant uses strike-through (<blink>) while {{dc|red{{=}}y}} uses red (<blink>).
