/*
**  TRAPQUERY -- trap queries which succeeded.
**
**	This module traps the current query into the file
**	specified by Trapfile.  It will open Trapfile if
**	it is not already open.
**
**	Parameters:
**		retcode -- the return code of the query.
**		name -- the name of the file in which to dump the
**			query buffer.
**
**	Returns:
**		none.
**
**	Side Effects:
**		Outputs the query buffer to Trapfile.
**
**	Called By:
**		go.
**
**	Files:
**		Trapfile -- the descriptor of the file in which to
**			trap the query.
**		Qbname -- the name of the query buffer.
**
**	Trace Flags:
**		none
**
**	Diagnostics:
**		none
**
**	Bugs:
**		If 'name' (that is, the {querytrap} macro) changes
**			during a run, the output file does not change.
**
**	History:
**		3/2/79 -- Grabbed from michael.
