set autosave
set autosave= { n | off}
When the autosave option is set to a positive number, Arbortext Editor saves any changes to the document every n seconds if there are unsaved changes. 600, or 10 minutes, is the default. The maximum setting is 7200, or 2 hours.
When Arbortext Editor performs an autosave for a document, it doesn't write to the original file. Instead, Arbortext Editor saves the document to a temporary file (based on the document name) with the extension .asv. If this file exists when the document is reopened, Arbortext Editor will prompt for which version to use. The autosave file, if any, is removed when the document is saved.
Examples
set autosave=60
set autosave=off
