CONSTRAIN PARAMETERS

The CONSTRAIN command allows the fit parameters to be examined, values changed, and constraint of parameters. This command itself is a sub-menu with the following commands:

EXIT: Return to FIT sub-menu

MODIFY: Make a change to one or more parameters. The number of the first parameter to alter and the number of the last parameter to alter are to be specified (0 means no parameter), followed by one of the following: CONSTRAIN, SET, UNCONSTRAIN. SET asks for the new value of the parameter.

VIEW: Display one or more parameter values, together with their name and constrained or unconstrained state.
