.. _G7RMqpcon:

**qpcon b <sign> [constant][*]ai [< > [constant][*] aj ...]**
   This command establishes constraints on parameters for a linear regression equation.  <sign> is '<', '=', or '>' ("<=" and ">=" also are accepted but are recorded as strict inequality constraints).  <constant> terms are optional scalar multiples for the respective parameters.  An asterisk may be included to clarify that the parameters are multiplied by the corresponding constant.  The parameters are denoted by <ai>, where 'i' is the position in the regression equation of the corresponding variable.  If a constant is included in the regression, then the parameters are denoted as a1, a2, ....  Right-hand-side terms are separated by either a '+' or '-'.

   Examples::

      qpcon 25.0 > a1          # constrain the constant
      qpcon 13.0 = 1*a2 + 1*a3 # constrain the sum of slope parameters

.. _G7RMquit:
	
**quit**
   This command quits the execution of *G7*.  Note that if any editor windows are open, they will be closed.  If you have any unsaved changes in these files, *G7* will ask you if you want to save the file.  Also, before exiting *G7* will store the workspace bank to file.
