One of our stored procedures makes a dynamic call to TSSAI, which is set up as AMODE ANY and RMODE 24. We recently updated our LE options for the WLM environment this procedure runs in to use ALL31(ON) and STACK(ANYWHERE), instead of ALL31(OFF) and STACK(BELOW). This change caused issues with our stored procedure because of the TSSAI call.. I have not been able to find references to a 31-bit module version in the documentation.
TSSAI is not available in 31 bit mode. It is only distributed as RMODE(24).
