 SAS can handle this with its' probit function (which is the inverse of
 the Z distribution):

 data backwrds;
 infile 'foo.dat';
 input p;
 z=probit(p);
 run;

 should do the trick!  Barring that, there may be some kind of
reference to the probit distribution in one of your books or manuals
which will guide you to the solution.  Good luck!
