  FORTH
       
          1.  An interactive extensible language using
          {postfix syntax} and a data stack, developed by Charles
          H. Moore in the 1960s.  FORTH is highly user-configurable and
          there are many different implementations, the following
          description is of a typical default configuration.
       
          Forth programs are structured as lists of "words" - FORTH's
          term which encompasses language keywords, primitives and
          user-defined {subroutines}.  Forth takes the idea of
          subroutines to an extreme - nearly everything is a subroutine.
          A word is any string of characters except the separator which
          defaults to space.  Numbers are treated specially.  Words are
          read one at a time from the input stream and either executed
          immediately ("interpretive execution") or compiled as part of
          the definition of a new word.
       
          The sequential nature of list execution and the implicit use
          of the data stack (numbers appearing in the lists are pushed
          to the stack as they are encountered) imply postfix syntax.
          Although postfix notation is initially difficult, experienced
          users find it simple and efficient.
       
          Words appearing in executable lists may be "{primitives}"
          (simple {assembly language} operations), names of previously
          compiled procedures or other special words.  A procedure
          definition is introduced by ":" and ended with ";" and is
          compiled as it is read.
       
          Most Forth dialects include the source language structures
          BEGIN-AGAIN, BEGIN-WHILE-REPEAT, BEGIN-UNTIL, DO-LOOP, and
          IF-ELSE-THEN, and others can be added by the user.  These are
          "compiling structures" which may only occur in a procedure
          definition.
       
          FORTH can include in-line {assembly language} between "CODE"
          and "ENDCODE" or similar constructs.  Forth primitives are
          written entirely in {assembly language}, secondaries contain a
          mixture.  In fact code in-lining is the basis of compilation
          in some implementations.
       
          Once assembled, primitives are used exactly like other words.
          A significant difference in behaviour can arise, however, from
          the fact that primitives end with a jump to "NEXT", the entry
          point of some code called the sequencer, whereas
          non-primitives end with the address of the "EXIT" primitive.
          The EXIT code includes the scheduler in some {multi-tasking}
          systems so a process can be {deschedule}d after executing a
          non-primitive, but not after a primitive.
       
          Forth implementations differ widely.  Implementation
          techniques include {threaded code}, dedicated Forth
          processors, {macros} at various levels, or interpreters
          written in another language such as {C}.  Some implementations
          provide {real-time} response, user-defined data structures,
          {multitasking}, {floating-point} arithmetic, and/or {virtual
          memory}.
       
          Some Forth systems support virtual memory without specific
          hardware support like {MMU}s.  However, Forth virtual memory
          is usually only a sort of extended data space and does not
          usually support executable code.
       
          FORTH does not distinguish between {operating system} calls
          and the language.  Commands relating to I/O, {file systems}
          and {virtual memory} are part of the same language as the
          words for arithmetic, memory access, loops, IF statements, and
          the user's application.
       
          Many Forth systems provide user-declared "vocabularies" which
          allow the same word to have different meanings in different
          contexts.  Within one vocabulary, re-defining a word causes
          the previous definition to be hidden from the interpreter (and
          therefore the compiler), but not from previous definitions.
       
          FORTH was first used to guide the telescope at NRAO, Kitt
          Peak.  Moore considered it to be a {fourth-generation
          language} but his {operating system} wouldn't let him use six
          letters in a program name, so FOURTH became FORTH.
       
          Versions include fig-FORTH, FORTH 79 and FORTH 83.
