MMENCODE help file X!`09Andy harper, 16-AUG-1994, Kings College London X1 MMENCODE XEncodes/Decodes a file to and from MIME format using either the BASE-64 or XQUOTED-PRINTABLE format. X XFormat: X $ MMENCODE `5Boptions`5D `5B-o output`5D input X2 Description XDocuments of any type can be sent via electronic mail if encoded using the XMIME conventions (MIME = Multimedia Internet Mail Extensions). The sender Xencodes the file using MIME and the recipient de\2E06it. Often the mail Xclient will contain facilities for automatic decoding of MIME message. VMS XMAIL does not and a certain amount of manual decoding is required. X XMMENCODE will: X X o Encode a file into MIME format for mailing to someone else X o Decode mail received from someone else back to its original format X XOnly the encoding types of BASE64 and QUOTED-PRINTABLE are recognized. XOther encoding types cannot be handled by MMENCODE. X2 Examples X $ MMENCODE -b -o TEST.B64\0906DAT X Encodes the file TEST.DAT into\170FB64, using the BASE64 X encoding format. X X $ MMENCODE -q -o TEST.QPR\0906DAT X Encodes the file TEST.DAT into\170FQPR, using the QUOTED- X PRINTABLE encoding format. X `20 X $ MMENCODE -u -b -o TEST.DAT\0906B64 X Decodes the file TEST.B64 from the BASE64 format back to its X original form in TEST.DAT. X X $ MMENCODE -u -q -o TEST.DAT\0906QPR X Decodes the file TEST.QPR from the QUOTED-PRINTABLE format back X to its original form in TEST.DAT. X2 Parameters XThe parameters to MMENCODE define the input file, which is required, an Xoptional output file, and various encoding options. The general form of the Xcommand is: X X $ MMENCODE `5Boptions`5D input X XWithout options, MMENCODE assumes: X * Output to the standard o\1706(SYS$OUTPUT) X * Encoding of input file X * QUOTED-PRINTABLE encoding type X X3 Options X -o file Specify the output file. X X -b Specify BASE64 encoding type X X -q Specify QUOTED-PRINTABLE encoding type (the default) X X -u Specify decode rather than encode X2 READ_MIME XREAD_MIME is a simple interactive procedure designed to ease the use of XMMENCODE for DECODING files. It will prompt for the input/output\2B06 and Xthe encoding type, and then run MMENCODE with the appropriate options. X XFormat: X X $ READ_MIME `5Binput`5D `5Bout\09061/2`5D X XPrompts are issued for any missing parameters. The third \1609 Xspecifies the encoding type - 1=BASE64, 2=QUOTED-PRINTABLE. X2 Usage_Notes XFiles to be decoded are received in the form of `60attachments' to a normal Xmail message. Each attachment can be in a variety of formats and is Xprefixed by a set of headers. These\0F08 should be removed before Xrunning them through the MMENCODE utility. Just pass the data portion of Xthe encoded attachment to MMENCODE. This may entail extracting the whole Xmessage into a file and then editing it to remove the extraneous headers. X XNote that MMENCODE can only deal with a small subset of the possible Xencoding formats. However, BASE64 and QUOTED-PRINTABLE and commonly used. $ call unpack [.MMENCODE]MMENCODE.HLP;1 980307653 "" 7 4 6 $! $ create 'f' XFrom:`09MX%"MX-List@WKUVX1.WKU.EDU" 9-MAR-1994 23:10:36.76 XTo:`09UDAA055 XCC:`09 XSubj:`09External Mime encoding/de\0906 X XReturn-Path: XReceived: from wkuvx1.wku.edu by bay.cc.kcl.ac.uk (MX V3.3 VAX) with SMTP; Wed V, X 09 Mar 1994 22:51:21 EST +-+-+-+-+-+-+-+- END OF PART 1 +-+-+-+-+-+-+-+- ================== RFC 822 Headers ================== Received: from newt.kcl.ac.uk by mail2.digital.com; (5.65 EXP 4/12/95 for V3.2/1.0/WV) id AA23213; Mon, 18 Sep 1995 11:02:49 -0700 Received: from kcl.ac.uk by newt.kcl.ac.uk with SMTP (PP) id <03176-0@newt.kcl.ac.uk>; Mon, 18 Sep 1995 19:02:27 +0100 Received: by bay.cc.kcl.ac.uk (MX V4.1 AXP) id 326; Mon, 18 Sep 1995 19:03:09 GMT Date: Mon, 18 Sep 1995 19:03:10 GMT From: Kings College London File Server To: everhart@star.zko.dec.com Message-Id: <00996981.DC7782EA.326@bay.cc.kcl.ac.uk> Subject: MMENCODE.1-OF-2
