Syntax:     
         SHOW/CONTEXT [name]
\ys\pa
         name = optional name of a context;
              if a name is given, the keyword OUTPUTI(5) will be set to 0
              if the context `name' has not been enabled or is set to the
              context level of context `name' (c_level > 0)
              if no name is given, all currently enabled contexts are
              displayed
	 name = -a
	      displays all existing contexts in $MIDASHOME/$MIDVERS/context,
	      enabled or not

Notes:
         The option of SHOW/CONTEXT with a context name is mainly useful in
         Midas procedures to find out, if a context `name' is set or not.
