Altimeter to SLP

I need to convert altimeter settings to (a) station pressure and (b) sea 
level pressure.  Since I'm not doing this in gempak (where everything 
happens magically and automatically), but rather PERL and FORTRAN, I need 
algorithms and not variable names.

The AMS's "Glossary of Meteorology" gives a description of how altimeter 
settings are determined, but doesn't give any useful numbers for going the 
other direction.  Wallace and Hobbs' "Atmospheric Science" gives an 
equation for calibrating altimeters (2.35), but my math isn't good enough 
for me to derive anything useful from that (although someone whose math is 
much better than mine is attempting this).

As usual, great amounts of karma are accrued by anyone who assists me.
