++ Manfred Mahlow's VOCS with ITEM and STICKY
+   - non-nested Vocs could be implemented by parsing the input-stream for the next token an EVALUATEing it. 
+     Nesting however would require that the rest of the input-stream would be available so that a Voc following a voc can still parse...
+   - ITEM and STICKY requires changes in the outer interpreter and the header structure.
+     ITEM words set the context to the voc that was active when ITEM was executed.
+     STICKY words extend the context one more parsed word.
