  FORTH
  
     1. <language> 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.
