The templates [[Template:P1|P1]] and [[Template:P2|P2]] simply return the first and second unnamed input parameter respectively. For example:<br />
* {{tlc|P1|foo|bar|baz}} returns {{P1|foo|bar|baz}}<br />
* {{tlc|P2|foo|bar|baz}} returns {{P2|foo|bar|baz}}<br />
<br />
These templates can be used inside other templates as an alternative to the {{pf|switch}} parser function, to switch between outputs based on whether the input is "1" or "2":<br />
* {{tlc|P{{<nowiki/>{1}}}|''output if 1''|''output if 2''}}<br />
<br />
Using <code><nowiki>{{#switch}}</nowiki></code>, this syntax is equivalent to<br />
* {{tlc|{{hash}}switch:{{<nowiki/>{1}}}|1{{=}}''output if 1''|2{{=}}''output if 2''}}<br />
except that the parser function strips whitespace between parameters whereas the templates don't.<br />

<br />
* {{tl|P-1}}, returns the last unnamed parameter<br />
