The whitespace setting only applies to the parsed content in which it appears. The setting is inherited by embedded [[Procedure Definitions]] and [[Custom Widgets]] definitions, but is not inherited by [[Macro definitions]].

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.
!! Procedure Definition with Set Widget
Procedures are implemented as a special kind of [[variable|Variables]] and so internally are actually defined with a <<.wlink SetWidget>> widget.
