ok. i will implement the code as you described.
i think i must download the source from the adress "git clone
git://git.savannah.gnu.org/pspp.git" using git. is this the current up-to-date
source?
How can i submit the changes? Before the PSPP, i submit some packages to cran
(R
project) wia ftp, but this is a complete GNU style.
Thanks.
Hakan.

syntax. is that right?
That's right. But I would start with something simpler. Say just
"QUICK CLUSTER x y z". The syntax parser can be a bit challenging
so keep it simple to start with, and add the options later.
You'll need to write a function of the form:
int cmd_quick_cluster (struct lexer *lexer, struct dataset *ds);
and register it in the file src/language/command.def
I suggest that you look at some of the existing examples to get
an idea of how it works. reliability.c is probably a good example.
also: I have no experience about coding GTK+
The first step will be to get the command written. You or someone
else can write the GUI for it later.
Good luck.
