UNSET and RESET

It is often convenient to assign a parameter value to the default. This assignment is accomplished with the command unset. For example, if the task histo had been run with inputs:

        in       = gauss
        region   =  
        range    = 0,1
        nbin     = 10

but you wanted to run histo with the default for nbin, you would type:

        histo% unset nbin

Multiple parameters can be unset on the same line. Thus, to assign both range and nbin to their default values, you would type:

        histo% unset range nbin

Then, typing:

        histo% inp

will result in miriad replying

        Task:   histo
        in       = gauss
        region   =  
        range    =  
        nbin     =

The command reset can be used to unset all parameter values (not just those of the present task selected); use with caution.
