/EXECUTE=command-file [argument]

    Invokes TECO and executes the TECO macro found in the command
    file. The argument, if specified, appears in the text buffer
    when macro execution starts. Blanks or special characters must
    be enclosed in quotation marks (" ").  For detailed information
    on the use of TECO macros, see the PDP-11 TECO Editor Reference
    Manual.

    The /EXECUTE qualifier is incompatible with the /CREATE and
    /MEMORY qualifiers.
