You can create your own variables using the Assign or Save Field commands or the Expression Builder. As with all variables, user-created variables retain their value until you change or delete them or quit Analyzer.
Note: Variables names that begin with an underscore are not deleted when you quit Analyzer. They are saved in the Analyzer Project.
Note: Variable names that begin with ASI_ are reserved and should only be used for for internal application purposes.
Note: If a field name forms part of the expression used to define a variable, the value for the field is taken from the current record at the time the variable is defined. The expression is evaluated once and the variable is assigned a value. When you subsequently move to a new record, the expression is not reevaluated.
For details on using the Assign command, see Assign. For details on using the Save Field command see Save.
To create a variable using the Expression Builder, do the following:
| 1. | Select Edit from the menu and choose Variables. Analyzer displays the Variables dialog. |
| 2. | Click [New]. Analyzer displays the Expression Builder. |
| 3. | Define the variable in the Expression text box. For more information, see Using the Expression Builder. |
| 4. | Enter a name for the variable in the Save As text box. |
| 5. | Click [OK]. |
