+init module ( – )<br >
+                First module, control is passed to on startup. Contains<br >
+                initialization routines. Also it is the last core module.<br >
+                All new modules on top of it comes as result of executing<br >
+                external source files.<br >
+<br >
+head <name> ( – ) compiles new dictionary entry without specifying<br >
+                new module type.<br >
+                ex: head myentry<br >
+<br >
+: <name> ( – ) creates new code module<br >
+; ( – ) ends module (immideate)<br >
+                ex: : hello ." hi there" ;<br >
+<br >
+const <name> ( n – ) defines new constant.<br >
+                ex: 2147483647 const max<br >

+<br >
+[ ( – ) set interpret mode (immideate)<br >
+] ( n – ) set compile mode and compile top stack element<br >

+                ex: : calculate - [ 4 MyConst1 + MyConst2 * ] ;<br >

+Dstrleft ( amo Dstr – )<br >

+<br >
+Dstrsp ( char Dstr1 Dstr2 – )<br >
+                Separate dynamic string in Dstr1 into two parts,<br >

+Dv ( addr – )<br >
+                Allocates empty dynamic string, and places it's handle<br >
+                into given address.<br >

+Df ( addr – )<br >
+                Reads dynamic string handle from given address and<br >
