# @(#)autowrite 8.3 (Berkeley) 2/17/95
Vi autowrite behavior, the fields with *'s are "don't cares".
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Commands that are affected only by autowrite:
Command File Autowrite? Action:
modified?
-----------------------------------------------
^Z Y Y Write file and suspend.
^Z Y N Suspend.
^Z N * Suspend.
# This behavior is NOT identical to :edit.
^^ Y Y Write file and jump.
^^ Y N Error.
^^ N * Jump.
# The new nvi command ^T (:tagpop) behaves identically to ^].
# This behavior is identical to :tag, :tagpop, and :tagpush with
# force always set to N.
^] Y Y Write file and jump.
^] Y N Error.
^] N * Jump.
# There's no way to specify a force flag to the '!' command.
:! Y Y Write file and execute.
:! Y N Warn (if warn option) and execute.
:! N * Execute.

Commands that are affected by both autowrite and force:
NOTE: the "force" flag is never passed on, i.e. the write
to the file caused by the autowrite flag is never forced.
