XML-INTO, Handlers and large blocks of data.

I am having to extract a very large block of xml(250,000 bytes) from within
an XML document envelope.

In looking at the documentation, it seems that XML-INTO using a handler
could handle this.

It seemed to indicate that if I did the following

p ResultHandler...
p b
d pi
d InOutCommArea...
d LikeDs(TD_CommArea)
d InBlocks...
d 32767a Varying
d Dim(35)
d Const
d InNumberOfElements...
d 10u 0 Value
/Free

Options = 'doc=file
path=S:Envelope/S:Body/ns2:ServiceResponds/operationResult';
XML-Into %Handler(ResultHandler : EmbeddComm)
%Xml(SoapFile: Options);

/End-Free

The documentation seems to indicate that it would take the data and break it
up into 32767 byte blocks and I would get the number of elements loaded.

That is not what happened. Instead I got one element loaded with 32767 bytes
of data and that was it.

This gets back that problem of processing large blocks of data in RPG.

Is there a trick to do this?
