Victor I believe that 13 bytes is the current lowest number that you can use to preserve uniqueness - (bits 8-111 which can be treated at 104-bit unsigned binary).

So, I thought I'd keep the first 10 bytes and the last 2 bytes [Programmable Field]. To my surprise STCKE returns non-zeroes in the bytes #13 and #14 - ???? 00C3CD5B F16F38C5 A8000000 01040002 Could someone explain what are these 2 bytes for? Also, how save is the assumption that the field can be compressed into 12 byte without losing its sysplex-wide uniqueness.
