John,
Thanks. Kinda thought that was the answer.
By copying the bug people on a note to Hugo I assume I have done as you suggest
to get the factor score request into the queue for consideration.
Hugo mentioned a posted wish list. Address?
I did check the developer wiki and I see that my earlier issues with the O/P
should be relieved within the new O/P goals. Just got your email re LO option.
Cool! Could be a great work-around until . . .
FYI your comment to John Deal re the wikis on the homepage, the user wiki link
seems broken. If relevant, I use Chrome 29.0 on OS10.8.4.
Cheers,
Mark

I can confirm, that this feature has not been implemented.
If it is important to you, then feel free to raise it as a wishlist bug.

I'm no expert in this routine, but there are some things PSPP still can not
do.
If you want to learn more about it, please check the documentation.
