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
- Using an AppConn
API, you can change the value of a variable using the
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.
