+1) a (currently) reduced set of functions:
+
+HASH: [5] [H.lib, H.new, H.disp, H.get, H.set!]
+
+2) building an associative array: {def H key value | ...}
+
+{def capitals
+ {H.new nyk New York, United States |
+        lon London, United Kingdom |
+        par Paris, France |
+        mos Moscou, Russia }}
+-> capitals
+
+3) displaying: {H.disp hash}
+{H.disp {capitals}}
+->
+[
+nyk: New York, United States
+lon: London, United Kingdom
+par: Paris, France
+mos: Moscou, Russia
+]
+
+4) getting a value from a key: {H.get hash key}
+
+{H.get {capitals} nyk} -> New York, United States
+{H.get {capitals} lon} -> London, United Kingdom
+{H.get {capitals} par} -> Paris, France
+{H.get {capitals} mos} -> Moscou, Russia
+
+5) adding a new (key,value): {H.set! hash key value}
+
+{H.disp {H.set! {capitals} bar Barcelona, Catalunya}}
+->
+[
+nyk: New York, United States
+lon: London, United Kingdom
+par: Paris, France
+mos: Moscou, Russia
+bar: Barcelona, Catalunya

+
+6) editing a key
+
+{H.disp
+  {H.set! {capitals}
+          nyk
+          {H.get {capitals} nyk} of America}} // adding "of America" to nyk
+->
+[
+nyk: New York, United States of America
+lon: London, United Kingdom
+par: Paris, France
+mos: Moscou, Russia
+bar: Barcelona, Catalunya
