Prompt

---

General Operation Statement

The Prompt function pauses the simulation and displays either a message and input field or a menu for selecting a choice. The value entered or selected is then assigned to the designated variable, array element, or attribute. To have Prompt present a menu, specify one or more choices as in the second following syntax example. The value already in the variable, array element, or attribute is used as the default value in the dialog box. One use of Prompt is to give the simulation user the option to change the operation time represented by a variable during a simulation.

Syntax

Prompt <string expression>, <name>{,
<choice1>:<expression1>,
<choice2>:<expression2>,
<choice3>:<expression3>...}

Examples
