OK - so you are using the old v4 UCD coding,
rather than the newer v5 handler-based approach

You can't.
The way that the UCD code works is to process the
request as a GET first (which has the side-effect of
settings the 'write_method' parameter.
    It then calls this write_method (several times)
to handle the SET processing.   See the file  AGENT.txt
for a description of how this works.

That's not how the agent works.
It calls the var_xxx routine *before* processing the SET request,
and will then automatically return the correct value - i.e. the value
that was included in the SET request.  You don't have to worry
about doing this yourself - it's handled by the agent framework.

Work with the agent - not against it :-)
