To connect an individual variable (say, XXX), open the dialog Connect variable XXX

1. Open a form with XXX value slot, and use the right mouse button to click on the slot.
2. Select Binding... from the right button menu.

To select a source

1. Switch the radio button, if necessary. There are 4 options
   1. use the given value
   2. use the initial value
   3. follow invoke procedure
   4. connect to a variable of ...
2. Complete the connection. The procedure depends on the radio-button that was chosen:
   • Option 1: Fill in the value field and click on the Connect button.
   • Option 2: Click the Connect button. This involves no further choice – XXX will be tied to its own initial value.
   • Option 3: Click the Connect button. This alternative, if available, sets the source for XXX to an object defined by an invoke algorithm. This source appears in the right window. Any attempt to browse the right window or to change the source will automatically switch the radio button to (4).
   • Option 4: Select a source:
     1. Select an object that contains the source variable or parameter from the left window.
     2. Select the variable (or parameter) from the outline in the right window.
     3. Click on the Connect button.
        Tip. Only compatible variables, parameters, and their placeholders are shown in the right window. If a placeholder cannot be opened, there are no compatible sources.
