His program is shorter than mine and uses just two registers. However, I tried to calculate Zeta(1.1) using his version and I had to stop after the HP-41CX emulator went on and on and on!

Hi Namir, I guess you must have something wrong in your V41 setup - or a bad transcription of the program code. I just ran the case x=1.1 using ZETAX in the SandMath (which implements Jean-Marc's Borwein algorithm) and it took 13.48 seconds to return the result 10.58444847. I also ran it for x=1.001, which returned 1,000.577289 in approximately the same time. Both examples done at the default speed, i.e. NOT in TURBO mode.
