MatrixButtonHelper syntax ?

[Gary Yonaites]

Here are the parameter's descriptive lines from the  
MATRIXBUTTONHELPER custom statement:

   <PARAMETER NAME=BUTTONLIST TYPE=TEXT>List of potential button  
objects in matrix frame, CR delimited</PARAMETER>
   <PARAMETER NAME=CLICKBUTTON TYPE=TEXT>Return object that was  
clicked on, or "" if none</PARAMETER>
   <PARAMETER NAME=BUTTONRECTANGLE OPTIONAL TYPE=TEXT>Return location  
of object that was clicked on, or "" if none</PARAMETER>

As you can see, the last parameter is optional but will return the  
objectinfo("rectangle") of the clicked button if a third parameter  
exists and a button was detected.
