James/Hector,
As of SPSS 7.5, the OUTFILE command in REGRESSION will
save an SPSS matrix file that includes unstandardized
regression coefficients and related variance estimates.
This file won't, as far as I know, include the standardized
Beta values, but it might be of some value to you anyway.
The file would be in an SPSS .sav format by default, but
if you're running production-type jobs to extract different
estimates now and put them in a separate database, you should
be able to approximate this in SPSS for Windows. You might,
for example, follow the REGRESSION specifications with a GET
FILE to call up the OUTFILE matrix you've just created and
save it immediately into a spreadsheet or database format
with SAVE TRANSLATE. There is probably a more elegant way of
doing this with the Script utility, though that's well outside
of anything I can advise on.
I hope I've understood your question and that this is useful.
