Raw Normal View History

Copying over the Hayes tester tests from C64 to msdos VolksForth. Names are adapted to DOS 8.3 file names, PETSCII adaptions of core.fth are reverted (DOS uses ASCII), the input test is disabled, since no way was yet found to inject keystrokes into dosbox. And some tweaks were applied to ans-shim.fth and the golden files to make the first tests (preliminary & core) to pass.

\ 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?...
