Syntax:  ap {message_specifier} {-control_args} command_line


Function:  places the text of the selected message(s) into a temporary
segment, catenates the pathname of this segment to the end of the given
command line, and executes the resulting Multics command line.  Each
message is processed individually.


Arguments:
message_specifier
   identifies to which messages the command line is to be applied.  If
   no message_specifier is supplied, the command line is applied to the
   current message.  For more information on message specifiers, type:
         help message_specifiers.gi
command_line
   is the Multics command line to which is catenated the pathname of
   the temporary segment before execution.


Control arguments:
-text
   specifies that the text of each message is to be included in the
   temporary segment.  (Default)
-no_text
   specifies that the text of each message is not to be included in the
   temporary segment.
-header, -he
   specifies that the header of each message is to be included in the
   temporary segment.  (Default)
-no_header, -nhe
   specifies that the header of each message is not to be included in
   the temporary segment.
-message message_specifier, -msg message_specifier
   specifies additional messages to which the command line is applied.


-include_deleted, -idl
   includes all messages in the mailbox whether or not they have been
   deleted when processing the message_specifiers to determine which
   messages will be processed.
-only_deleted, -odl
   includes only those messages which have been deleted.
-only_non_deleted, -ondl
   includes only those messages which have not been deleted.  (Default)
-delete, -dl
   marks the specified messages for deletion on exit from read_mail
   if all messages are successfully processed.
-no_delete, -ndl
   does not mark the messages for deletion.  (Default)
-reverse, -rv
   processes the messages in descending numeric order.
-no_reverse, -nrv
   processes the messages in ascending numeric order.  (Default)


Notes:
This request will acknowledge any messages requiring acknowledgement
unless -no_acknowledge is specified on the read_mail command line.

The command line may not modify the contents of the temporary segment.

-no_text and -no_header are mutually exclusive.

The supplied command line need not be enclosed in quotes.  However, if
there are (), [], or "'s in the command line which should be processed
by the Multics command processor, they should be enclosed in quotes to
prevent processing by read_mail's request processor.


Examples:
The request line:

      apply /frogs/ "do ""copy &1 &!; eor &! -dl"""

may be used to issue a separate output request for each message which
contains the string "frogs".

Historical Background

This edition of the Multics software materials and documentation is provided and donated
to Massachusetts Institute of Technology by Group BULL including BULL HN Information Systems Inc. 
as a contribution to computer science knowledge.  
This donation is made also to give evidence of the common contributions of Massachusetts Institute of Technology,
Bell Laboratories, General Electric, Honeywell Information Systems Inc., Honeywell BULL Inc., Groupe BULL
and BULL HN Information Systems Inc. to the development of this operating system. 
Multics development was initiated by Massachusetts Institute of Technology Project MAC (1963-1970),
renamed the MIT Laboratory for Computer Science and Artificial Intelligence in the mid 1970s, under the leadership
of Professor Fernando Jose Corbato. Users consider that Multics provided the best software architecture 
for managing computer hardware properly and for executing programs. Many subsequent operating systems 
incorporated Multics principles.
Multics was distributed in 1975 to 2000 by Group Bull in Europe , and in the U.S. by Bull HN Information Systems Inc., 
as successor in interest by change in name only to Honeywell Bull Inc. and Honeywell Information Systems Inc. .
