hi all,

when there is a need to determine the TCBSENV (TCB ACEE) in charge for a
given RACHECK call, determining it for the current TCB is quite easy:

L     R14,PSATOLD-FLC(0,0)    LOAD CURRENT TASK CONTRO
ICM   R15,B'1111',TCBSENV-TCB(R14)                    
BNZ   tcbacee_given

my question: 

1) does racf only honor the TCBSENV of the current task, or is there a need
to check the entire TCB tree above, means checking the TCBSENV field of the
mother tcb, and its mother ... in order to identify any non-zero TCBSENV field?

2) is there a risk for an infinite loop in the tcb-mother-child structure by
just looping until TCBOTC = 0?

thanks for any info or code.

best
stephen
