CHANGE/DIRECTORY direc
	change the default (current) directory for MIDAS
\us\pu
Purpose:
	  Change the default (current) directory for MIDAS
\up\sy
Syntax:  
          CHANGE/DIRECTORY direc 
\ys\pa
          direc = string specifying the new default directory in the host
              system syntax;
\\
              if no directory string is entered, the current host default
              directory is used

Note:   
          Since MIDAS executes its applications in a child process (subprocess
          for VMS) which leaves no traces after termination, one cannot simply
          use the host command "$cd ..." ("$SET DEF ..." in VMS) to change 
          the default directory once you are in a MIDAS session.
          Instead, you must use the MIDAS command CHANGE/DIRECTORY.

Examples:
\ex
          CHANGE/DIR /home/ns2c/kbanse/test
            On a Unix machine set the MIDAS default directory to
            " /home/ns2c/kbanse/test ". All MIDAS data files and procedures
            will be taken from that directory and new files will be created
            there.
\xe\ex
          CHANGE/DIR [KBANSE.DATA.93APR] 
            On a VMS machine set the MIDAS default directory to
            " [KBANSE.DATA.93APR] ".
\xe\ex
          CHANGE/DIREC
            Reset MIDAS default directory to current host directory.
