So, quick BOTEC (or rather, back of Lisp interpreter which is my desk calculator of choice), assuming 7 bln total population and 7.111mln for Serbia (from Wikipedia): 5]> (/ 7000000000 (/ 7111024 4l0)) 3937.548234965878332L0 [6]> (/ 7000000000 (/ 7111024 1l0)) 984.387058741469583L0 This gives about 4k z/OS and 1k VSE worldwide. Quite in agreement with estimation given few posts earlier by Phil Smith, if I recall correctly. However, I do not claim that my method is worth anything. -- Regards, Tomasz Rola -- ** A C programmer asked whether computer had Buddha's nature. ** ** As the answer, master did "rm -rif" on the programmer's home ** ** directory.
