1. What is Automatic mode? In Manual mode all commands and required data are entered by the user. These commands, data and main results are copied to the Output file. This information allows the design session to be repeated. In Automatic mode, commands and data are read from an input file with no entry required from user.

2. Reasons for Automatic mode zUser can complete a design in two or more sessions zRepeat a design with a different storm zRevise and compare the design of one or more components zAdd or insert commands in Manual mode to change hydrology simulation or design

3. Files used in Automatic mode ‘Output’ is the file created in a previous Manual session. ‘New Output’ is modified output file created during Automatic design session. ‘Miduss.Mdb’ is a database file created by the Create Miduss.Mdb command. Create Miduss.Mdb Edit Miduss.Mdb Run Miduss.Mdb Automatic

4. Structure of the Database Command Index Parameter value Description, data or results

5. Advantages of a Database zDirect access to records speeds processing zDatabase file can be ‘bound’ to a grid zFile can be viewed, edited and used as input source simultaneously zSetting a command as a negative number causes a continuous Automatic run to stop and revert to step-by-step EDIT mode or switch to Manual mode zAutomatic processing can re-start where it was halted

6. Steps to Run Automatic mode  Create the input database Miduss.Mdb using the Creat Miduss.Mdb command zReview and/or Edit the database - e.g. change Command numbers to negative value to halt processing.  Use the Run Miduss.Mdb command to process the file in any of three modes EDIT, STEP or RUN

7. Using the Control Panel The Control Panel is displayed when the Run Miduss.Mdb command is used RUN starts continuous processing of the data STEP executes commands one by one without any chance to modify data EDIT executes next command and lets you alter data and [Accept] the result
