Establishes the default file specification that the debugger uses
    when searching for command procedures.

    Format

      SET ATSIGN  file-spec

1  –  Parameters

 file-spec

    Specifies any part of a file specification (for example, a
    directory name or a file type) that the debugger is to use
    by default when searching for a command procedure. If you do
    not supply a full file specification, the debugger assumes
    SYS$DISK:[]DEBUG.COM as the default file specification for any
    missing field.

    You can specify a logical name that translates to a search list.
    In this case, the debugger processes the file specifications
    in the order they appear in the search list until the command
    procedure is found.

2  –  Description

    When you invoke a debugger command procedure with the execute
    procedure (@) command, the debugger assumes, by default, that the
    command procedure file specification is SYS$DISK:[]DEBUG.COM. The
    SET ATSIGN command enables you to override this default.

       @ (Execute Procedure)
       SHOW ATSIGN

3  –  Example

  DBG> SET ATSIGN USER:[JONES.DEBUG].DBG
  DBG> @TEST

      In this example, when you use the @TEST command, the debugger
      looks for the file TEST.DBG in USER:[JONES.DEBUG].
