Model Examples

Several model examples are included in the Development Kit installation and are located in your \<VHI install directory>\models folder. Each model emulates a different host application to provide an interactive example of how the Design Tool is used to create a model. To simulate this emulation, the Design Tool is used in conjunction with the Host Emulator. Before viewing a model example, make sure that the Design Tool is open and the Host Emulator is started.

The example models demonstrate strategies for modeling block mode 3270 applications and character mode VT applications. Some particularly important or difficult areas of these models are discussed to assist you in discovering solutions that will work for your host application. While each host application is unique, these techniques will help you avoid the most common problems. Look through all the examples for ideas about what you might want to use in your model.

You can also review examples for individual methods in the Visual Basic Methods Reference online help.

The following 3270 host application models are included in your installation and can be used with the Host Emulator:

• CCSDemo — Provides a good example of multicolumn recordsets and accessing customer data.
• CICSAccts — Provides a good example of operation conditions, recordsets, and compound procedures.
• SIDemo — Provides a good example of recordset selection and insertion.
• Purchases — Provides a good example of recordset implementation in a model.

The following models are included in the Development Kit installation, but cannot be used with the Host Emulator:

• pine — A model of a VT Terminal host application. Even if you are modeling a 3270 application, you may find that the Pine model contains some applicable tips.

Notes:

• Only specific search criteria will result in data being returned.
• The Host Emulator is capable of emulating 3270 and 5250 host applications only.
