UNSET

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

Task:   smalod
  in       = /home/miriad/SMAdata/sma/040329_09:37:37/
  out      = mymiriad.uv
  rxif     = 1
  rsnchan  = 16
  sideband = 0
  nscans   = 35,950

but one wanted to run smalod with the default for rsnchan, you would type:

   histo% unset rsnchan
