1  ATTACH
   Switches control of your terminal from your current process to
   another process.

   The ATTACH command allows you to move between processes that you
   create with the SPAWN command. For example, while you are editing
   a file, use the SPAWN command to move to a subprocess (Mail) to
   read a new mail message. Then enter ATTACH to move back to the
   editing session. If you want to read another new mail message,
   enter the ATTACH command to move back to the Mail subprocess you
   already created.

   Format

     ATTACH  [process-name]
 

2  Parameter
 

process-name

   Indicates the name of the subprocess to which you want to
   connect. If the subprocess name contains spaces, special
   characters, or lower-case letters, then the subprocess name must
   be enclosed in quotation marks.
 

2  Qualifier
 

/PARENT

   Indicates that you want to attach to the parent process of your
   current process. If you did not access the Mail utility by using
   the SPAWN command, Mail displays an error message. You cannot
   specify the process-name parameter with the /PARENT qualifier.
 

2  Examples

   1.$ EDIT VACATION.TXT
        .
        .
        .
<Do>

     Command: SPAWN MAIL
     MAIL> READ
        .
        .
        .
     MAIL> ATTACH MAGNANI
        .
        .
        .
<Do>

     Command: SPAWN MAIL
     MAIL>

     This example shows how to spawn a subprocess (MAGNANI_1) to
     invoke Mail and use the ATTACH command to move between Mail
     (MAGNANI_1) and a DECTPU editing session (MAGNANI). The ATTACH
     command allows you to transfer control between subprocesses.

                                  NOTE

      Always enter the SPAWN command to create a new process and
      the ATTACH command to connect to a process that already
      exists. For more information on the SPAWN and ATTACH
      commands, exit from Mail and enter HELP SPAWN or HELP ATTACH
      at the DCL prompt.
