abort-file-io: system variable

Default value: -3

If the user presses the abort key when Epsilon is reading or writing a file, Epsilon asks whether to abort the file input/output operation. If the user says to abort, the file reading or writing primitive returns an error code, EREADABORT or EWRITEABORT, respectively. This variable changes Epsilon's behavior; EEL code may set it using a save_var statement to one of these values: A value of ABORT_IGNORE (0) makes Epsilon ignore the abort key during file I/O. A value of ABORT_ASK (-3, the default) makes Epsilon ask the user as above and return an error code. A value of ABORT_ERROR (-2) make Epsilon return the error code without prompting first. The value ABORT_JUMP (-1) doesn't ask either; it calls the check_abort( ) primitive, which typically aborts the entire command.
