       system cmdstr1 ?cmdstr2...?
              Concatenates  cmdstr1,  cmdstr2 etc with space sep
              arators (see the concat command) into a single com
              mand and then evaluates the command using the stan
              dard  system  shell.   On  Unix  systems,  this  is
              /bin/sh  and  om Windows its command.com.  The exit
              code of the command is returned.

              This command differs from the exec command in  that
              system  doesn't return the executed command's stan
              dard output as the result string, and  system  goes
              through  the  Unix shell to provide wildcard expan
              sion, redirection, etc, as is  normal  from  an  sh
              command line.
