Problem Note 61214: The SYSRANDOM macro variable fails to store the seed used in PROC MCMC
 |  |  |  |  |
If you omit the SEED= option in PROC MCMC, or you specify a seed that is less than or equal to zero, the SYSRANDOM macro variable does not store the system seed used. Without the value of the generated seed, it is not possible to reproduce simulations.
