There is only 1 reason for data exception, and that is that you are running on hardware which has the vector facility but vector is not enabled. It is operation exception if running on older hardware. Most likely you are running back-level z/OS ... you must be on the right level of z/OS with z15 exploitation ptfs installed in order to use the vector facility. Remember that the z15 vector registers partially overlay the old FP registers, so operating system support is needed to work right :) Now if you really want to have fun, start using the dilithium CRYSTALS signatures with your z15 (for Quantum safe signatures) ... some astonishing capability.
