Break Statement

Please answer this as soon as possible: how do i break from a loop / return from a macro based on some condition

Please have a look at this code

#macro ( countTabbedSection $position )
position = $position
#set ($loopend = $alSections.size() - 1)
#foreach ($count in [$position..$loopend])
 #set( $sectiondataobject = $alSections.get($count) )
 #if ($sectiondataobject.getIsTabbed()==1)
 sectiondataobject.getIsTabbed() = $sectiondataobject.getIsTabbed()
 #else
  ## i want to break this loop here
 #end
#end
#end ## end of macro


#set( $count = 0 )
#foreach ($sectiondataobject in $alSections)
 #countTabbedSection( $count )
 #set( $count=$count+1 )
#end

 

Thanks

break and continue would be useful though.
It would be nice if Velocity supported those statements.

We have no break statement.  Generally, people do this with some kind of
$running flag and an #if()

I've am implementing a break; in another project, and will report back on
how well it works.
