Oriel is a scripting language released with the Power Tools series of instructional books written by the LeBlond Group.

The former was the Oriel interpreter, which when invoked would prompt the user to choose a script file for execution.

The latter gave the user the ability to create custom executables by bundling a script within a copy of the interpreter.

An Oriel program will always possess a main window over which a dialog box of this type would appear.

The following code gives that window a title, maximizes it, and instructs it to remain open until the user closes it.
