 *  $Log: qp_query.h,v $
 *  Revision 1.14  1999/08/31 08:47:38  couet
 *  - A new set of PAW commands using Neural Networks.
 *    These new commands are using the MLPfit package.
 *
 *  Revision 1.13  1996/05/12 15:13:54  maartenb
 *  - Replaced the handling of variables. The handling of variables is now
 *  fully dynamic and there is no other limit than the commonblocks to the
 *  number of var's in a query.
 *
 *  Revision 1.12  1996/04/23 18:38:54  maartenb
 *  - Add RCS keywords
 *
