Module:ATC code to template name

Module documentation[view] [edit] [history] [purge]

Translates an ATC code passed as an unnamed parameter to the function "translate" into the name of the navbox template associated with that ATC code on Wikipedia.

Use:

{{#invoke:ATC code to template name|translate|X00}}

The template returned does not have the Template: prefix.
