MM Manual


Some of the operation of MM is controlled by variables. MM was designed with variables so that you could change some of the things it does to match your preferences.


To see a list of variables, use the show command. If you type just show, you will see a series of set commands that show each variable and its current setting. At the end, you also see define commands if you have created any mail-aliases with define.

set aliases-use-groups no
set append-signature never
set auto-startup-get yes
set autowrap-column -7
set browse-clear-screen yes
set browse-pause yes
set check-interval 300
set clear-screen yes
set continuous-check no
set control-d-automatic-send no
set control-e-editor yes
set control-l-confirm no
set control-n-abort ask
set crt-filter /usr/ucb/more -d
set default-bcc-list
set default-cc-list
set default-fcc-list
set default-from
set default-mail-type mbox
set default-read-command next

If you type show ? with a question mark, you see a list of mail-aliases (if you created any) and variables without their values.

MM>show ? confirm with carriage return
  or mail alias, one of the following:
  or variable, one of the following:
 aliases-use-groups         append-new-mail            append-signature
 auto-create-files          auto-startup-get           autowrap-column
 browse-clear-screen        browse-pause               check-interval
 clear-screen               continuous-check           control-d-automatic-send
 control-e-editor           control-l-confirm          control-n-abort
 crt-filter                 default-bcc-list           default-cc-list

Lastly, the show command can also be used to see the current setting of any specific variable.

MM>show aliases-use-groups
set aliases-use-groups no


For information about what any variable does, use the command help set and the name of a variable.

MM>help set aliases-use-groups
SET ALIASES-USE-GROUPS NO/yes  -  whether to show mail-aliases in sent mail

With the usual NO setting, if you use a mail-alias when you type in an
  address, it is changed in the outgoing mail to show the real addresses.
  If the mail-alias was for a list of addresses, the people receiving
  your mail will see who else got the message, and be able to send replies
  (or regular mail) to the other people.

If you change it to YES, the people receiving your mail will see only the
  mail-alias in the address.  This might be desirable if it is a long list
  of addresses that would appear as a very long header field.

For more help, type "help" and one of the following:
(at any prompt:)  save-init   set   show   define   who


The variables all have what are called default settings. A default, in general, is the value of a variable in the absence of any specific instruction. If you have never changed any variables, all the values shown by show are the defaults.

The values are of two basic types:
