One minor thing to remember that if you are dealing with lengths that are not a

environment where your code is executing that might be a non-trivial or
non-desirable exercise.

Our four day course "z/OS Assembler Programming Part 4: z/Architecture and z/OS"
includes this instruction, as well as all the non-privileged instructions
introduced with all the zSeries machines. See
