[Zope] DTMLMethod Question

[James W. Howe]

I've got a folder which contains DTMLMethods which are used to format a 
"news" article in a certain way.  One of the methods is responsible for 
actually displaying the article contents, the others are responsible for 
generating various navigational components.  I'm now designing a new view 
which is also going to display a news article, plus some other stuff.  The 
major difference is that this view is only going to show a subset of 
information.  I would like to reuse the article display code but I'm not 
exactly sure how to do it.  What I would like to do is retrieve the first N 
characters from a news article and then have my method format 
it.  Something like:

<dtml-var "formattingMethod(???, <dtml-var articleContent size=500>)">

I'm not fluent enough in all the nuances of how you call a DTMLMethod 
rather than get results via reference/acquisition.  I suppose I could pass 
the length restriction as a parameter and if that parameter didn't exist 
the full article would be retrieved.  I would rather simply pass the 
article contents and let the method format what it is given.

Any help would be appreciated.

Thanks.
