Support forums and a basic question

Hello everyone,

I am new to SPARQL and am learning my way around, thanks in large part to
Bob Ducharme's book "Learning SPARQL" .  Is this an appropriate forum for
general SPARQL questions?  What other mail lists and forums are available
for basic-through-advanced questions?

My basic question is on how I can format a query result.   This query:

SELECT ?codeLabel
WHERE
{
  ?code skos:inScheme code:treatment .
  ?code skos:prefLabel ?codeLabel .
}

Returns the result:

codeLabel
- - - - - - - - - - -
Active
Placebo


I would like to format the result to appear as:

Treatment Arm
- - - - - - - - - - -
Active
Placebo


Is there a way to do this within the SPARQL query without post-processing?
FYI I am currently using ARQ for querying a .ttl file directly.

Cheers,

Tim W.  (SPARQL newbie)
