1  COMPRESS
   Makes an indexed mail file smaller by recovering space that is
   left by deleted mail messages. When you compress a file, the
   following steps occur:

   1. A temporary file named MAIL_nnnn_COMPRESS.TMP is created.
      (nnnn is a hexadecimal, 4- or 8-digit number.)

   2. The contents of the file to be compressed are copied to the
      temporary file, and the temporary file is then compressed.

   3. The original uncompressed file is renamed with a file type
      .OLD.

   4. The newly compressed file is renamed from
      MAIL_nnnn_COMPRESS.TMP back to its original name.

   Format

     COMPRESS  [file-spec]
 

2  Parameter
 

file-spec

   The name of the mail file to be compressed. If a file name is not
   specified, Mail compresses the mail file that is currently open.
   If there is no open file, Mail opens and compresses the default
   mail file.
 

2  Qualifier
 

/OUTPUT

      /OUTPUT=out-file-spec

   The name of the compressed file. Note that if you specify an
   output file, the mail file is compressed and renamed. This leaves
   you with 2 copies of your mail file: the original uncompressed
   version and the new compressed version that has the name that you
   specified when you entered the /OUTPUT qualifier.
