        [SIC\]@ Macro_Name [Par1 [Par2 [...]]]

    Reads commands from  macro  Macro_Name  and  executes  them.   Up  to  8
    parameters  can  be  given.  These parameters will be substituted to the
    tokens 1, 2, ..., 8  found  in  the  body  of  the  macro,  even  within
    character  strings  (e.g.  Par1 for token 1).  Default file extension is
    program dependent (usually the  program  name,  or  .pro),  and  can  be
    changed using command SIC EXTENSION.  All commands will be echoed to the
    terminal when executed if the VERIFY  switch  is  on  (See  command  SIC
    VERIFY).

    Macros (as any other text files) can be edited  using  a  standard  text
    editor  (EDT,  TPU,  EDU  or EVE on VMS, Emacs or Vi on Unix, NotePad or
    WordPad on MS-Windows), by typing command EDIT with the macro file  name
    as argument (see EDIT).
