Variables

The Variables dialog box allows you to configure model variables. You can initialize model variables in several ways using the Host Integrator:

Using the Design Tool, you can use this dialog box to define and initialize model variables.
Using the Host Integrator Server, you can override a variable value stored in the model file using session pooling.
Using an AppConn API, you can change the value of a variable using the SetModelVariable method.
Note: If host data is accessed through a procedure, you should avoid using variables in combination with a procedure unless there is no other alternative. You may find you need to use ReadVarFromAttr and WriteVarToAttr commands to pass data between screens, but all client data should be passed in and returned through the table itself.

The primary advantages of using variables are to provide abstraction from entities and to enable attributes to be accessible from all parts of the Host Integrator. See the Host Integrator Server Reference for more information about initializing variables from a session pool model variable list during server execution.
