Peter, I absolutely agree. A couple of weeks ago I needed to do quick research on the possibility of implementing decimal floating point and when I went to the PoOPs there were no examples. I wonder if the PoOPs author(s) are expecting everyone to use Dr. Ehrman's Assembler Language Programming for IBM System z™ Servers textbook? It's a great resource for beginning programmers but not for writing system-level product code. Actually, it might be of benefit to others if there was a repository of code snippets like SRST, TRT, TR for parsing/replacing data, pulling data from a dataspace, using access registers and the points you highlighted in your response.

SRST is much, much faster than TRT but still orders of magnitude slower than the vector instructions. -- This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
