+\ VERSION 1.2
+\ THIS PROGRAM TESTS THE CORE WORDS OF AN ANS FORTH SYSTEM.
+\ THE PROGRAM ASSUMES A TWO'S COMPLEMENT IMPLEMENTATION WHERE
+\ THE RANGE OF SIGNED NUMBERS IS -2^(N-1) ... 2^(N-1)-1 AND
+\ THE RANGE OF UNSIGNED NUMBERS IS 0 ... 2^(N)-1.
+\ I HAVEN'T FIGURED OUT HOW TO TEST KEY, QUIT, ABORT, OR ABORT"...
+\ I ALSO HAVEN'T THOUGHT OF A WAY TO TEST ENVIRONMENT?...

+\ checks that postpone works correctly with words with special
+\ compilation semantics
+
+\ by M. Anton Ertl 1996
+
+\ This file is based on John Hayes' core.fr (coretest.fs), which has
+\ the following copyright notice:
+
+\ (C) 1995 JOHNS HOPKINS UNIVERSITY / APPLIED PHYSICS LABORATORY
+\ MAY BE DISTRIBUTED FREELY AS LONG AS THIS COPYRIGHT NOTICE REMAINS.
+
+\ my contributions to this file are in the public domain
+
+\ you have to load John Hayes' tester.fs (=tester.fr) and coretest.fs
+\ (core.fr) first
+
+\ These tests are especially useful for showing that state-smart
+\ implementations of words with special compilation semantics,
+\ combined with a straight-forward implementation of POSTPONE (and
+\ [COMPILE]) do not conform to the ANS Forth standard. The essential
+\ sentences in the standad are:
+
+\ 6.1.2033 POSTPONE CORE
+\ ...
+\ Compilation: ( <spaces>name -- )
+
+\ Skip leading space delimiters. Parse name delimited by a space. Find
+\ name. Append the compilation semantics of name to the current
+\ definition.
+
+\ 6.2.2530 [COMPILE] bracket-compile CORE EXT
+\ ...
+\ Compilation: ( <spaces>name -- )
+
+\ Skip leading space delimiters. Parse name delimited by a space. Find
+\ name. If name has other than default compilation semantics, append
+\ them to the current definition;...
+
+
+\ Note that the compilation semantics are appended, not some
+\ state-dependent semantics.
+
+\ first I test against a non-ANS solution suggested by Bernd Paysan
+
+: STATE@-NOW ( -- F )
+ STATE @ ; IMMEDIATE
+
+: STATE@ ( -- F )
+ POSTPONE STATE@-NOW ;

+

+\ semantics.
