Records: A form of data structure                                                                                               This module allows somewhat high-level data structures to be    built and used. It's just one block of code, so it won't waste  heap.                                                                                                                                                                                                                                                           variable object                                                 : +! dup @ rot + swap ! ;                                       : record: create here object ! 4 , does> create @ dup , allot ; : field: create object @ dup @ , +! does> @ + ;                 : cell 4 ;
