       1msystem 4m22mcmdstr124m ?4mcmdstr224m...?
              Concatenates   4mcmdstr124m,   4mcmdstr224m etc with space separators (see
              the 1mconcat 22mcommand) into a single command and then evaluates the
              command  using the standard system shell.  On Unix systems, this
              is 1m/bin/sh 22mand on Windows its 1mcommand.com22m.  The exit code of the
              command is returned.

              This  command  differs  from  the  1mexec  22mcommand  in that 1msystem0m
              doesn't return the executed command's  standard  output  as  the
              result string, and 1msystem 22mgoes through the Unix shell to provide
              wild card expansion, redirection, etc, as is normal from  an  1msh0m
              command line.
