Bert Jung <>:
If you make your program rclass and return everything as scalars,
including coef estimates, you can easily get everything out.  Make
sure your program ends with
. eret clear
and then -simulate- will automatically keep all the r() contents.
Note also that resetting the seed inside the program is a very bad
idea and often destroys any good qualities of the pseudorandom number
generator.  You can get the current seed from c(seed) instead.
