   9: **  TRAPQUERY -- trap queries which succeeded.
  10: **
  11: **	This module traps the current query into the file
  12: **	specified by Trapfile.  It will open Trapfile if
  13: **	it is not already open.
  14: **
  15: **	Parameters:
  16: **		retcode -- the return code of the query.
  17: **		name -- the name of the file in which to dump the
  18: **			query buffer.
  19: **
  20: **	Returns:
  21: **		none.
  22: **
  23: **	Side Effects:
  24: **		Outputs the query buffer to Trapfile.
  25: **
  26: **	Called By:
  27: **		go.
  28: **
  29: **	Files:
  30: **		Trapfile -- the descriptor of the file in which to
  31: **			trap the query.
  32: **		Qbname -- the name of the query buffer.
  33: **
  34: **	Trace Flags:
  35: **		none
  36: **
  37: **	Diagnostics:
  38: **		none
  39: **
  40: **	Bugs:
  41: **		If 'name' (that is, the {querytrap} macro) changes
  42: **			during a run, the output file does not change.
