I looked that up or browsed the macro there is no reference rmode/amode 31
in the macro.
I did try sysstate amode64 generated the same code.

The combination with a mask of B'0111' limits addressing to 24 bits.
It does work in AMODE 31 and 24, but not on a 360.

My mistake was the BALR in AMODE 31 doesn't kill bits 1 - 7

Just wonder if you code an estate if that will get control before open abend

The fact that your code is AMODE 31 does not mean that the access method MUST
be above the line.
The actual expansion had an XR 15,15 before the ICM.
Why do you think that there is an issue? BALR does not change the AMODE.

I can't see your read macro call, but if it's inline the macro
is going to generate the DECB inline with the code. Since the
DECB must be 24 bit addressa
