======================================================================
int dbnumcols(dbproc)

Returns:
The number of columns in the current set of results. If there are no
columns, dbnumcols returns 0.
======================================================================

The implication is that the query was a select, but it won't break
the protocol to return 0 for other cases.  Probably a good idea if
that is what Sybase does.  That is how the current CVS appears to
deal with things.
