Jeremy, I tested your solution and it works, BUT, this is true if utility macro itself contains wikitext like example above. If utility itself call other macro or have some scripts, then it will fail, look at the below case
\define mac2(p) {{{ [<__p__>split[]addprefix[c]] }}} \define utility(a, b) This is //$a$// and ''$b$''. <$macrocall $name="mac2" p=<<__a__>> /> \end \define test(a,b) <$set name="newText" value=<<utility a:"""$a$""" b:"""$b$""">>> <$text text=<<newText>> /> </$set> \end <<test italic bold>> The output is: This is //italic// and ''bold''. <$macrocall $name="mac2" p=<<__a__>> /> While I expect; This is //italic// and ''bold''. cictcaclcicc --Mohammad -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
