Change the Period of Record

  1. Open the control file (*.ctl) in a text editor.
  2. Revise the beginning (iystr) and/or ending years (iyend); note that input data must be complete for the period of record selected.
  3. Save the revised control file (*.ctl); consider saving with a new file name to preserve the original file.
