pForth for OpenVMS VAX -- sources and provenance
=================================================

Program      pForth 2.0.1 (its banner says "PForth V2.0.0": upstream tag v2.0.1 still has
             PFORTH_VERSION_NAME "2.0.0" in csrc/pf_guts.h; the source built is the v2.0.1 tag), "a portable ANS-like Forth
             written in ANSI C", by Phil Burk, with Larry Polansky, David Rosenboom and Darren
             Gibbs; support for 64-bit cells by Aleksej Saushev.

             tag v2.0.1, commit 3956a7fd77845a04006973a7ba97a4b65d437e7e (9-JAN-2023, the newest

Changes made for VMS (five patches, each in its own file, all small; the rest is unchanged):
  01-no-stdint.diff    pforth.h: PF_NO_STDINT supplies the integer types (DEC C 6.4 for VAX has no
                       <stdint.h> and no 64 bit integer type)
  02-system-word.diff  pfcustom.c: new words SYSTEM ( c-addr u -- n ), CLOCK, CLOCKS/SEC
  03-stdio-sleep.diff  stdio/pf_io_stdio.c: sdSleepMillis() for the "stdio" platform (upstream does
                       not define it there, so that platform did not link); VMS uses LIB$WAIT
  04-no-round.diff     pf_float.h: fp_round() without the C99 round(), which the VAX C library lacks
  05-no-shrink-file.diff stdio/pf_fileio_stdio.c: RESIZE-FILE to a smaller size reports an error
                       (freopen(NULL, ...) crashes the DEC C run-time library on VAX)
  BUILD_PFORTH.COM     new: the build procedure (CC, LINK, dictionary)

The patches (as .DIF files) and BUILD_PFORTH.COM are in [.DOC] of the installed kit.

Fig-Forth (if the kit includes [.FIG]): VAX-11 fig-Forth Version 2.0 by Rodrick A. Eldridge for the
Central Iowa Forth Interest Group (CIFIG), Iowa State University, 1985; "public domain", further
distribution must include its notices (they are in the MACRO source and FIGFORTH.MEM). Built unchanged
with MACRO and LINK from FGFORTHV2.MAR (renamed FIGFORTHV2.MAR as the archive's own AAARENAME.COM does),
from the DECUS VAX85 symposium collection (vax85d/forth).  SHA-256 of the files used:

  *.FIG           66 library screens, unchanged

Build: 15 modules with DEC C 6.4 on a VAXstation 4000/90 (OpenVMS VAX 7.3), /FLOAT=G_FLOAT,
about 1 min 10 s, then the dictionary with "PFORTH -i system.fth" (7 s).  Sources, patches and
the recipe with hashes are in the distribution this kit came with.
