Passing Parameters Between Frames
You can use the current values from a parent frame to set the values for fields on a child frame. A value that you pass between frames in this way is called a parameter. Parameters let you use the same data with different frames.
When you use parameters, Vision lets you move data from the parent frame to the child frame so that the user:
• Does not have to re-enter the information
• Is ensured of working with the correct data
For example, a user might display a record on a Browse frame about a specific customer order, then call an Update frame to change that record. Disable user qualification processing and pass values from the Browse frame to the Update frame. When the user calls the Update frame:
– The Update frame displays the customer record that currently appears on the Browse frame.
– Vision automatically increases the price of each item in the order by 10% on the Update frame (in effect, passing the value of the price field plus 10%).

Pass a Parameter to a Frame shows how to specify these parameters and provides additional examples.
