JACK is a program for designing drip and sprinkler irrigation systems, preparing list of materials, and tracking irrigation equipment inventory. JACK runs on the IBM PC, XT, AT, PS/2 and compatible machines using MS-DOS or WINDOWS. It requires 640K byte RAM memory, a graphic card (CGA, EGA, VGA or Hercules).
A. JACK's Main Menu
This is the menu displayed when you start JACK. It gives you the choice between the program's main parts which are: 1. Initialization, 2. Design, 3. List of Materials. 4. Mapping
1. The Initialization part is where you define the monitor and printer control codes, the data units, the header of the printed reports, the head loss equation parameters, the monetary unit used and the uniformity equation used and create the libraries of emission devices, pipe series and tapes.
2. The Design part in where you design blind lines, tapes, laterals, manifolds units and networks and analyze existing lines.
3. The List of Materials part is where you handle records of vendors, materials (inventory items), and added costs, and projects.
4. The Mapping part in where you can create simple drafts of designs.
B. The Initialization Part
The initialization part has the following options:
1. Emission Devices Library 2. Series Library 3. Tape Library 4. System Configuration 5. Header 6. Units 7. Name of Monetary unit 8. Equation parameters & maximum velocity 9. Discharge uniformity equation
1. The Emission Device Library: With this option you handle the records of the Emission Device library used in the different design options of the design part. A record of an Emission Device includes its Pressure-Discharge curve, its nominal discharge and its price. In this part you add data of new Emission Devices, modify data of existing Emission Devices, erase Emission Devices, and produce Emission Device reports. The data of the Emission Device library can later be used in the design parts instead of defining the curve again and again in new designs.
2. The Pipe Library With this option you handle the records of the pipe library used in the different design options of the design part. The pipe record is entered as a series of pipes with an increasing size of diameters. EXAMPLE: a pipe series can be all the possible diameters to be used as laterals. Each pipe in a series is defined by its diameters its Hazen Williams roughness coefficient C and by its price per unit length. In this part you can add data of new pipe series, update data of an existing series, erase a series and produce reports.
3. The Tape Library With this option you handle the records of the tape library used in the tape design option of the design part. A record of a tape includes the Pressure-Discharge curve for one unit length of the tape, its nominal unit length discharge its price and the internal diameter of the tape. In this part you add data of new tapes, modify data of existing tapes, erase tapes, and produce tape reports. The data of the tapes library can later be used in the design parts instead of defining the curve again and again in new designs.
4. System Configuration With this option you can suppress the color and the sound of JACK and change the control codes of the printer and the screen according to the equipment model used.
5. Units With this option you change the input and output units and their validity limits. You can choose a complete unit system like the metric or the English, or you can change the units of an individual data item.
6. Header With this option you can change the header of the printed reports produced by JACK. The header is the first three lines of any printed report and it can include any printable characters.
7. Monetary unit With this option you enter the monetary unit (e.g. $) used where the program is used.
8. Equation parameters & maximum velocity With this part you can define the parameters used in the computation of head loss for laterals and non laterals and the maximum velocity allowed.

D. The List of Materials Part This part includes the following options:
1. Vendors
2. Materials(Inventory Parts)
3. Added Costs
4. Projects
E.
1. Vendors With this option you handle the records of the vendors library. A vendor is a supplier of one of the materials (inventory parts) used in the designs. A vendor's record includes the vendor's full name, address, telephone number, contact person and a comment.
2. Materials (Inventory Items) With this option you handle the records of the inventory items used in the different designs. A material's record includes the material full name, its vendor, the purchase and sale cost, the minimum and maximum stock and a comment.
3. Added Cost With this option you handle the definition of added costs which are not direct material costs like taxes, labor or freight. A specific added cost can be related to the cost of the materials only like sales tax that is a percentage of the material costs, related to other added costs only or related to all the total of materials and added costs. It can also be a fixed dollar amount.
4. Projects (Assembly Items) With this option you handle assembly items and produce the list of materials. You can define a project that is made from materials (inventory items), added costs and other projects. The capability of using other projects in the definition makes it easy and fast to define complicated projects and lists of material. This feature is extremely useful when you have to estimate a cost of a project for bidding. The report of this part include the list of materials and orders from the different vendors. EXAMPLE: To define a complicated block, you initially define a lateral project, next you define a manifold project that is made of a few lateral projects, next you define a control unit project and finally you define the entire block which is made of a several manifolds and one control unit.
