@node Save, Set, Return, Commands

@iftex
@syntax Save.
@end iftex
@example
Syntax: SAVE [ @r{filename } ]
@end example
@pindex Save

Save some or all of the current macros, variables, and vectors
in file @code{filename}
(if omitted the default is to use the value of @code{save_file} in your 
@file{.sm}
file, or failing that @file{sm.dmp}). The current history buffer may also
be saved, as the macro @code{all}.

You are prompted for whether you want to save
variables, vectors, and macros (which includes @code{all}, the current
playback buffer). Macros beginning
## are @emph{not} saved, as they are assumed to be system macros.
Variables and vectors whose names start with a `_' are assumed to be
temporaries, and are not saved either.

   The opposite to SAVE is RESTORE (@pxref{Restore}).
You may want to use the MACRO
DELETE WORD command to undefine macros from e.g. the @file{utils} macro file.
See, for example, the macro @code{sav} (which can be overloaded).

If VERBOSE (@pxref{Verbose}) is greater than 0, some extra information
is printed.
