The call
tag lets you call a method without inserting the results
into the DTML output.
call
tag syntax:
<dtml-call Variable|expr="Expression">
If the call tag uses a variable, the methods arguments are passed
automatically by DTML just as with the var
tag. If the method is
specified in a expression, then you must pass the arguments yourself.
Calling by variable name:
<dtml-call UpdateInfo>
This calls the UpdateInfo
object automatically passing arguments.
Calling by expression:
<dtml-call expr="RESPONSE.setHeader('content-type', 'text/plain')">
