I am sorry but I don't follow you...  What should be a method?  My PHP 
script? If that is what you are referring to, then how will that affect 
the placement of the output from the script when it is evaluated? And 
how do I call it? Perhaps I need a better example to help me grok this?  
Keep in mind that what I am trying to accomplish is to executed an 
embedded multi-line PHP script inside a Javascript segment, all of which 
is inside a .jsp file.....  At the moment the PHP script is being 
executed, but the output, being done via echo statements in the script 
(and called PHP functions) is all being placed at the beginning of the 
output document, not at the place where the evalPHP call is made...

Also, are the changes I made to the evalPHP function correct? I presume 
that the first argument of evalPHP (String arg....) is the string that  
contains the actual script that I want to execute. I have concatenated 
all the PHP script lines into a single String variable and this is what 
I pass to evalPHP.

Thanks again for all your time and help!   Marc...
