equation(s) of the form option=value where option is one of caption, title, or width; specify options for the Maplet application
The GetExpression() calling sequence displays a Maplet application that prompts the user to enter an expression. This expression is returned to the Maple session. If the user does not enter an expression, an exception is raised.
The GetExpression sample Maplet worksheet describes how to write a Maplet application that behaves similarly to this routine by using the Maplets[Elements] package.
The opts argument can contain one or more of the following equations that set Maplet application options.
caption = string

title = string
Specifies the Maplet application title. By default, the title is Get Expression.
