In general I don't think you can get SAS and Stata to do this.
A simple, although embarrassingly inelegant, solution would be to have
Stata (or SAS) generate the random numbers. Then output them to a text
file and have the other program read them in. You would need to be
careful about precision issues, but otherwise it should work fine.

Subject: st: Stata vs. SAS (random number generation)
Dear Statalist,
I would like to know if it is possible, and if so how, to have Stata and
SAS
generating the same sequence of random numbers.
I've tried setting the same seed value in both packages with no success
(see
example of the command and output below).
Any help will be much appreciated.
Cheers,
JP
*************** command ***************
Stata command
set seed 1
g z1 = uniform()
set seed 2
g z2 = uniform()
SAS command
Z1=UNIFORM(1);
Z2=UNIFORM(2);
*************** output ***************
