This is done by typing a $ followed by the operating system command you want to have executed. After this command has been finished you can continue your work inside MIDAS. Since MIDAS executes its applications in a child process (subprocess for VMS) which leaves no traces after termination, you cannot simply use the host command <TT>$ cd</TT> (Unix) (<TT>$ SET DEF</TT> in VMS) to change the working directory once you are in a MIDAS session. Instead, use the MIDAS command <TT>change/direc</TT> for that purpose. <BR> See Chapter <A HREF="node22.html#monitor-and-syntax">3</A> for a detailed discussion of the interaction of Midas with the host system. <P> <P> =31 =3 =1999 <P> <BR><HR> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-09</I> </ADDRESS> </BODY> </HTML>
