         When calculations are saved for later recall, they are
         saved under a PROJECT name that you name. If an entire
         project needs to be deleted to free disk space, the key
         F7 will remove the entire project. However, if you want 
         to edit a project and remove only selected tag no's., this
         can be done by pressing Function key F6 and using delete
         to edit. The file (tag no.) will be removed from the project
         file, but a space will remain in the database file where it
         resided. It is necessary to purge the database to free up
         the disk space. Press F8 to reindex the database. A message
         "Enter Database Name or "ALL" with a default of "ALL" will
         appear. Press ENTER for default.

         When a sizing calculation is completed, you may press F3
         to enter the result in a multi-phase calculation. As additional
         calculations are performed, they may be added, at which time
         total results are calculated. Results from any screen can be
         added by using the F3 key, or may be deleted using the delete

         coefficient of discharge will also be entered automatically.
         If you select "OTHER", it will be necessary to manually enter

        When a calculation is completed, you may press function key
        F8 to save the results to a database. The prompt will ask
        for a file name, defaulting to the last file name entered.
        From the main menu you can select function key F6 to recall
        saved files. You will be asked for the file name, then press
        <ENTER> and a listing of all records saved under this file
        name will be displayed. Use the cursor key to highlight the
        selection and press <ENTER> for retrieval. If a retrieved
        file is to be saved, you will be asked if you wish to over-
        write the existing file. Pressing "Y" will add this as a new
        record. If "N" is entered, this record will overwrite the
        previously saved record.
