Dynamic memory
                        --------------


dynal ( size -- handle )
                Allocate dynamic memory block and return it's handle.

dynde ( handle -- )
                Deallocate dynamic memory block.

dynp ( handle -- addr )
                Returns pointer to memory where dynamic block
                data begins.

dyns ( handle -- size )
                Returns size of dynamic block.

dynresize ( NewSize handle -- )
                Nondestructively resize dynamic block.

dync@ ( addr handle )
                Read one byte from dynamic block.

dync! ( byte addr dynhandle )
                Write one byte to dynamic block.

dyn@ ( addr handle )
                Read 32 bit number from dynamic block.
                Address will spacify, whitch number, not byte.

dyn! ( 32BitNum addr dynhandle )
                Write 32 bit number to dynamic block.
                Address will spacify, whitch number, not byte.

dyncon ( size "name" -- )
                Allocate dynamic block with specified size, and
                create constant honding its handle.
                ex: 100 dyncon MyNewBlock

dyn. ( handle -- )
                Write contenc of dynamic memory block to screen.
