Ok, I won't direct you anywhere :-), but if anyone else has the same
problem, there is an unit in (/pc/ts/)tspas18.arc to do just this. 
Available by anonymous ftp from chyde.uwasa.fi. 

... I'll backtrack a bit.  Also see Press & Flannery & al:
Numerical Recipes, Cabridge University Press.  Hope this helps.

(Incidentally, this has been a very frequently asked question, but
for some reason it has been dormant for a few months, kinda lying
low, biding its time, or whatever.  You wouldn't believe how many
messages we had about this way back when.)
