> ScriptEdit (Somak Software) is a supercharged replacement for

The ScriptEdit system consists of three different parts: The
ScriptEdit desk accessory; an external command (XCMD) that provides
HyperCard-to-ScriptEdit communications; and two special HyperTalk
scripts that link the desk accessory and XCMD together and correctly
activates ScriptEdit when it is selected from the Apple menu.
