Virtual variables pages
Several context-sensitive pages in the Variable Properties dialog box are displayed for virtual variables. The pages that are displayed depend on the operator that was used to create the virtual variable.
See also: To view and modify variable property settings.
Operands page
The Operands page is displayed on the Variable Properties dialog box when any virtual variable is selected.

Description |
|
Operator |
The operator type that is being applied to create the virtual variable. |
|
Operand(s) |
The virtual or raw variable(s) that are being operated on to create the selected virtual variable. Select a specific operand using the Operand list. When available click Add New Operand to add an operand or click Remove Last Operand to remove an operand. |
|
Description |
A large text box that displays a summary of the selected operator, including applicable data types, Dataflow Toolbox category/categories, and required Echoview modules. |
For full descriptions of individual operators, see the Operators reference page.
You can change the operand(s) for a virtual variable, but not the operator itself.
