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

    Stores the current program section context on the top of the
    program section context stack, an internal assembler stack.

      .SAVE_PSECT [LOCAL_BLOCK]

    LOCAL_BLOCK

    An optional keyword that specifies that the current local label is
    to be saved with the program section context.

    It leaves the current program section context in effect.  The
    program section  context  stack can hold 31 entries.  Each entry
    includes the value of the current location counter and the maximum
    value  assigned to the location counter in the current program
    section.

    The alternate form of .SAVE_PSECT is .SAVE.
