ENDCLI [-C]

* Exits you from ZShell back to the AmigaDOS CLI prompt or Workbench.
* If the  option  "-c" was specified, it will clear ZShell as a
   resident : only in low memory situations needed.
* Instead of using ENDCLI you can simply press the ESC key or click
  on the close gadget, if available.

eg.   endcli
      endcli -c
