I am trying to automatically generate PPM P5 files.
In order to write the binary part of the files, I am using
put_code/1
maybe, considering you are building a non-text file, you'd be better
off having Prolog use a binary stream, in which case you'd be using
the put_byte/1 built-in.
consider this, for instance:
11:56:56$ gprolog
GNU Prolog 1.4.1

| ?- open(foo, write, _FOO, [type(binary), alias(foo)]),
set_output(foo),
put_byte(0), put_byte(1), put_byte(2), put_byte(3),
close(foo).
(1 ms) yes
| ?- halt.
11:57:05$ od -b foo
0000000 000 001 002 003
0000004
11:57:10$ ls -l foo
-rw-r--r-- 1 spa staff 4B Nov 1 11:56 foo
11:57:19$
hope this helps
