VMS Help MACRO, VAX MACRO Assembler, Directives, .END  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Terminates the source program.

    .END [symbol]

    symbol

    The address (called the transfer address) at which program
    execution is to begin.

    No additional text should occur beyond  this  point  in  the
    current source  file  or  in  any  additional  source  files
    specified in the command line for this assembly.  If any additional
    text  does  occur, the assembler ignores it.

    The transfer address must be in a program section that  has  the
    EXE attribute.

    When an executable image consisting  of  several  object  modules
    is linked,  only  one  object  module  should  be  terminated by an
    .END directive that  specifies  a  transfer  address.   All  other
    object modules should be terminated by .END directives that do not
    specify a transfer address.
