A function can call other functions.

Note that this is parsing $1 and $2 before they're defined. At the  
time the Markup is being defined $1 and $2 are blank.  Try:

Markup( 'map', '_begin', '/\(:map(-location\s|\s)(.*?):\)/ie',  
"CvtMarkup('\$1', '\$2')" );

or:

Markup( 'map', '_begin', '/\(:map(-location\s|\s)(.*?):\)/ie',  
'CvtMarkup("$1", "$2")' );

I don't fully understand how to escape the function call properly;  
someone else might have to help you with that one if these don't  
work.  What you want is to store the function and variable names so  
that Markup can run them later.


Let me know if that doesn't help.
