BAYES method and initial estimate bounds

Hi all, If bounds are specified in the $THETA statements for initial estimates, what, if any, effect do they have when the BAYES method is used? I initially thought they might work in conjunction with the prior specifications to implement truncated priors. However that does not seem to be true because statements like "IF(ABS(THETA(1)) > 10) EXIT 1 14" sometimes get tripped even when THETA(1) is bounded between -10 and 10 in the $THETA statement. Happy Holidays, Bill
