Template:High-use {{#invoke:Message box|mbox}}Template:High-use
The templates P1 and P2 simply return the first respectively second unnamed input parameter respectively. For example:
- Template:Tlc returns foo
- Template:Tlc returns bar
These templates can be used inside other templates as an alternative to the Template:Pf parser function, to switch between outputs based on whether the input is "1" or "2":
Using {{#switch}}, this syntax is equivalent to
except that the parser function strips whitespace between parameters whereas the templates don't.
