This tiddler describes the different ways in which Procedures can be defined.
Procedure Definition Pragma
Procedures are created using the Pragma: \procedure at the start of a tiddler. The definitions are available in the rest of the tiddler that defines them, plus any tiddlers that it transcludes.
\procedure my-procedure(param) This is the procedure text (param=<<param>>) \end
Note that the Pragma: \whitespace setting is inherited from the parsing context in which the procedure definition occurs. That means that a tiddler containing multiple procedure definitions only needs a single whitespace pragma at the top of the tiddler, and the setting will be automatically inherited by the procedure definitions without needing the pragma to be repeated.

Global procedures can be defined using the SystemTag: $:/tags/Global.

The tag SystemTag: $:/tags/Global/View/Body is used to define procedures that should only be available within the main view template body and the preview panel.
