Below not tested, but believed correct
Using variables in the called macro
\define macroname() $(var1)$ $(var2)$ {{textreference}}
<$set name=var1 value={{textref}} emptyValue="default">
<$set name=var2 filter="[all[current]get[fieldname]]" emptyValue="default">
<<macroname>>
</$set></$set>
Also From TiddlyWiki <https://tiddlywiki.com/#Macros>
A similar effect to a parameterised macro call can be produced by setting
variables <https://tiddlywiki.com/#Variables> around a transclusion
<https://tiddlywiki.com/#Transclusion>.
Calling tiddler
<$set name=var1 value={{textref}} emptyValue="default">
<$set name=var2 filter="[all[current]get[fieldname]]" emptyValue="default">
{{||templatetiddler}} <!-- note {|| which operated on the calling tiddler
as currentTiddler -->
</$set></$set>
templatetiddler
<<var1>>
$(var1)$ <!-- not sure-->
{{!!fieldname}} and other text references from calling tiddler
Note: A design pattern I use is to always make a macro operate on the
currentTiddler, you can always use the tiddler widgety or a list to alter
the currentTiddler variable to have a macro operate on a listed or other
tiddler.
If anyone can think of another method do share
