Do you mean conversion to printable hex, e.g. convert x'1234' to x'f1f2f3f4'? These days, I use the TROT instruction.

Something that I'd like to see inPoOps is an example of using UNPK and TR to convert binary to hexadecimal. -- Shmuel (Seymour J.)

Or am I late to the party and there have already been such SHARE sessions that I missed? If I have one particular beef with the PoOPS writing team it is that there are significant sets of instructions with no usage examples, z13+ vector instructions being only just the latest.

We use SIMD *heavily* for character-based operations and the speed is incredible! Doing 16 operations at once sure is preferable to doing just one! ijs... ;-) -- This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
