VMS Help SET, CONTROL  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Enables or disables the Ctrl/Y or the Ctrl/T function. Pressing
    Ctrl/Y interrupts a command and returns you to the DCL command
    level. Pressing Ctrl/T momentarily interrupts a command to print
    a line of statistics.

    SET CONTROL=T requires that SET TERMINAL/BROADCAST be set for the
    information to be displayed at your terminal.

    Format

      SET CONTROL  [=(T,Y)]

      SET NOCONTROL  [=(T,Y)]

1 - Parameter

 (T,Y)

    Specifies that T (Ctrl/T) or Y (Ctrl/Y) be enabled or disabled.
    If you specify only one character, you can omit the parentheses.
    If you do not specify either T or Y, Y is the default.

2 - Examples

    1.$ SET NOCONTROL=Y

      The SET CONTROL command in this example disables the Ctrl/Y
      function as well as most Ctrl/C functions.

    2.$ SET CONTROL=T

      The SET CONTROL command in this example enables the Ctrl/T
      function.

    3.$ SET NOCONTROL=(T,Y)

      The SET CONTROL command in this example disables both the
      Ctrl/T and Ctrl/Y functions.

    4.$ <Ctrl/T>
      NODE22::SMITH 16:21:04 (DCL) CPU=00:03:29.39 PF=14802 IO=18652 MEM=68
      $ SET NOCONTROL=T
      $ <Ctrl/T>

      As shown in this example, when you press Ctrl/T, the system
      displays the appropriate information. The SET NOCONTROL=T
      command disables the Ctrl/T function. Now when you press
      Ctrl/T, no information is displayed.
