SET -- set a preference setting during runtime

A preference setting created via a %SET macro is usable by the topic containing the %SET statement, and in any other topics %INCLUDing or %INCLUDEd when rendering the topic TML. This is unlike list or META style preference settings which are only set when the base topic is loaded, and never set during macro expension when an %INCLUDEd topic is processed.

A TMPL:DEF template definition containing %SET macros will also add those values to the current scope as if these settings have been parsed as part of the base topic's text.

Setting a preference setting in a list like in

   * Set foo = %SEARCH{...

or in META settings will store the text of the TML expression.

The equivalent %SET statement:

%SET{"foo" value="%SEARCH{..."}%

will store the result of the TML expression as a consequence of the parser processing macros inside-out-left-to-right.

Parameters

Parameter	Description	Default
"name"	Name of preference to set
value	Value to set it to

Examples

To cache the result of another macro use %SET{"search_result" value="%SEARCH{...}%"}%. The result of the value expression will be temporarily bound to the variable %search_result% and might be used within the scope of the current topic being processed, or in %INCLUDing or other %INCLUDEd topics.

Note that this macro does NOT expand format tokens that are used to alter the macro processing sequence. ($percent, $dollar, …).
