How to use <<__param__>> in Tiddlywiki? What is the correct syntax and use

[Mohammad]

I want to know if the below syntax and usages of <<__param__>> is valid in TW.

\define mymac(param)

 <$reveal type="nomatch" default="Empty" text=<<__param__>> >

    <div class="card">$param$</div>

 </$reveal>

\end

Actually my question is the valid syntax for using <<__param__>>.

How about this?

\define mymac(param)

 <$reveal type="nomatch" default="Empty" text=<<__param__>> >

    <div class="card"><<__param__>> </div>

 </$reveal>

\end

All your examples are valid. The key to understanding the double underscore syntax is to remember that it turns a parameter name into a variable name. Thus __param__ is valid anywhere that a variable name is valid.

Best wishes

Many thanks Jeremy!

Actually I am starting using it to make sure I can send any complex combination of content to this macro!
