A session editor with incremental execution functions
Niklas Holsti · Software Practice and Experience · 1989
Abstract Editing the script of an interactive session on‐line can replace or enhance common interaction techniques and help to separate the user interface from the computation. We describe a text editor that executes scripts incrementally, co‐operating with application programs to undo and redo script parts. The user edits the input part of a transcript, and the editor updates the output part. The transcript becomes a clear and reusable document. The applications choose the backtracking steps, and can thus evolve gradually. Extensions to non‐linear dialogues are in progress.
