Sorry about the BS.

I was saying that I'm revisiting Forth using Pforth and Brodie's
"Starting Forth". I'm of course working through his examples.
Pforth doesn't seem to support the words SPACE and SPACES.
Should I be loading another dictionary to get those words? TIA ..

That would be Phil Burk's pforth?

I've never compiled this system but SPACE and SPACES are included
in the file 'system.fth'. I see mention of

pforth -i system.fth

which claims to rebuild the system so you might try that.

I'll give it a shot! Thx. If all else fails, I've got gforth
installed as well. Probably should stick with it.

Maybe I need to scoop it from his site? I'll give it a shot.

[dxforth]

I managed to compile a base pforth executable under Windows. system.fth
is located in the 'fth' directory so I moved the exec there and ran:

pforth -i system.fth

which generates pforth.dic. After that pforth boots with SPACE SPACES etc.
loaded.

I'm on a Linux box! All I have (or can find) is "pforth.dic". How
do you go about compiling "a base pforth"? You new from source?

[dxforth]

I used the TCC Win compiler and the pforth sources here:

https://github.com/philburk/pforth

Never used Linux. Perhaps someone here can suggest how to compile
for your platform.

[Richard Owlett]

Which Linux?
pforth is available in current Debian repository.

You may need to install build tools for your flavour of linux - ask.

view pforth manual at:
http://www.softsynth.com/pforth/pf_ref.php#Compiling-pForth-System

follow link to look at build instructions here:
How to Compile pForth on Unix or Mac
https://github.com/philburk/pforth/wiki/Compiling-on-Unix

then:
mkdir .../github.com/philburke # make place for sources

git clone https://github.com/philburk/pforth.git # pull in source
cd pforth/ # select project folder
ls # take a quick look

cd platforms/unix/ # select unix build folder

make all # run build

ls # take a peek

./pforth # run executable

Sorry, pre-post check failed, Jan Coombs

[Sidney Reilley]

I know! That's what I'm running on my antiX Linux box.

The only way I got it to work is by telling it where the default
dictionary was. In your instructions, you simply executed `pforth'.

pforth -d ~/bin/pforth.dic

However, it works well so far.

Why don't you use gforth instead of pforth? Gforth is very full
featured and there is probably an installable package for your Linux
distro. E.g. if you are using Debian, say "apt-get install gforth".

Great. OTOH I was unable to build the f/p version

#define PF_SUPPORT_FP

The compiler spewed out errors. Knowing little-to-nothing about C
I didn't pursue it further.

[tom d]

My version has space defined and its:
: space bl emit ;

and you can define spaces as:

: spaces 0 do space loop ;

This is just a basic definition. You could add checks for an empty stack.

[dxforth]

Strictly speaking that should be:

: spaces ( +n -- ) 0 max 0 ?do space loop ;

The inbuilt '0 MAX' is a historical artefact. Programmers computing
padding spaces didn't have to worry about 'negative' values.

The default unix build here seems to include f/p (Debian, Intel, 64b):
1234.5678e1 f. 12345.68 ok

> #define PF_SUPPORT_FP

The unix makefile here contains:
XCPPFLAGS = -DPF_SUPPORT_FP -D_DEFAULT_SOURCE -D_GNU_SOURCE
and other instances of "fp".
Where is the
#define PF_SUPPORT_FP
in yours?

[dxforth]

There was no makefile for Win other than a project file for VisualStudio.
Not knowing how to make one, I just created a file of includes. That
worked until I declared PF_SUPPORT_FP ...

#define PF_SUPPORT_FP

Here on Slackware64 it works with no problems whatsoever. Of course SPACE / SPACES do exist in its dictionary:

#v+
PForth V27-LE/64, built Feb 19 2018 01:56:44
pForth loading dictionary from file /usr/share/pforth/v28/pforth.dic
File format version is 9
Name space size = 120000
Code space size = 300000
Entry Point = 0
Cell Size = 8
Little Endian Dictionary

space ok
Stack<10>
4 spaces ok
Stack<10>
12 spaces ok
Stack<10>
#v-

Multiple spaces in my reply have been "compressed" by news server. They are correctly displayed "locally" ofc.

Multiple spaces in your reply were delivered unchanged by NNTP servers.
They are replaced by a single space in the Google Groups web-interface only.
