The OS.Process structure provides functions for manipulating processes in an  operating system independent manner. 
<CODE><B>include</B> <A HREF="http://www.cs.bell-labs.com/~jhr/sml/basis/pages/os-process.html#OS_PROCESS:SIG:SPEC">OS_PROCESS</A><BR>
<B>val</B> <A NAME="SIG:CML_OS_PROCESS.systemEvt:VAL:SPEC" HREF="#SIG:CML_OS_PROCESS.systemEvt:VAL">systemEvt</A> <B>:</B> string -&gt; status event         <BR>
<DT> <A NAME="SIG:CML_OS_PROCESS.systemEvt:VAL"><CODE>systemEvt <VAR>cmd</VAR>
asks the operating system to execute the command <VAR>cmd</VAR> as 	  a sub-process, and returns an event for synchronizing on the 	  termination of the sub-process.           Raises <A HREF="http://www.cs.bell-labs.com/~jhr/sml/basis/pages/os.html#SIG:OS.SysErr:EXN:SPEC">SysErr</A> if the command cannot be executed.           
          Note that, although this function is independent of the operating           system, the interpretation of the string <VAR>cmd</VAR> depends           very much on the underlying operating system and shell.
