VAXTPU SEND — VMS 5.2

 SEND

 Passes data to a specified subprocess.  If you specify a buffer or a range
 as the data to pass to a subprocess, the lines of the buffer or range are
 sent as separate records.  The subprocess must have already been created
 with the CREATE_PROCESS built-in so that the output can be stored in the
 buffer associated with the subprocess.  (See help on CREATE_PROCESS.)

 Syntax

    SEND ({buffer | range | string}, process)

 Parameters

    buffer     A buffer whose contents you want to send to the subprocess.

    range      A range whose contents you want to send to the subprocess.

    string     A string you want to send to the subprocess.

    process    The process to which you want to send data.

 Examples

 1.  SEND ("directory", Joyce_1);

     Sends the DCL DIRECTORY command to the subprocess named Joyce_1.

 2.  The following procedure uses SEND to pass a command to a subprocess in
     which MAIL is running; the command to be sent to the subprocess is
     obtained by using READ_LINE:

     PROCEDURE user_send_mail
     ! Create buffer and window for running subprocess
         grs := CREATE_BUFFER ("mail_buffer");
         grs := CREATE_WINDOW (1, 22, ON);
     ! Map the mail window to the screen
         UNMAP (MAIN_WINDOW);
         MAP (grs_mail_window, grs_mail_buffer);
     ! Create subprocess and send "MAIL" as first command
         subp1 := CREATE_PROCESS (grs_mail_buffer, "MAIL");
     ! Position to mail window and get next command
         POSITION (grs_mail_window);
         cmd1 := READ_LINE ("Mail_subp> ", 20);
         SEND (cmd1, subp1);
     ENDPROCEDURE;
