Creating Advanced Expressions

You can create advanced expressions for use in While and Do Until loop types.

You can perform all the functions that the Calculator provides except that you can enter only a single logical expression. The Calculator component allows you to have multiple assignment statements. For more information about the Calculator component, see Calculator Component.

  1. Double-click the Loop component icon .
    The Loop Component Editor appears.
  2. From the Loop Component Editor, click While or Do Until from the Loop Type list.
  3. Click the Advanced tab.
  4. Define, edit, and test your expression.
  5. Your conditional expression may never be satisfied in some cases; therefore, you can specify a Maximum number of iterations after which Isight assumes the conditional expression is satisfied.
  6. Select OK to save your changes and to close the Loop Component Editor.
