Thanks Todd. I think you are referring to CVDG which is what I had used but didn't yield the expected results. Splitting a 128bit binary integer into 2 64bits and then a CVDG didn't convert it as expected. I will probably try that out again. I used Java Big Integer for a simple 128bit arithmetic and the outputs from z13 and Java did not match.

A full 128-bit value will not fit into a 31-digit decimal number." ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
