True, it really is like comparing apples to coconuts when counting lines. Also, you introduced another variable, ISPF (and I assume other software would fit in as well), which I wouldn't have thought to include when trying to compare the Linux kernel to the z/OS ... ? Nucleus is it called?
Plus the Linux kernel can be stripped down to bare necessities and the executable size can be quite small. Anyway, it was interesting to hear what people said about this topic, but now I don't think it's very easy to compare Linux to Windows to z/OS without going into specific details.

That's a serious question. Is a line of assembler equivalent to a line of PLX, C, REXX, Java, ISPF DTL? etc. Are comment lines included in the count? Does everyone use the same metrics? I think there is approximately no hope of getting a valid comparison of operating system size based on a LOC count (with your favorite prefix before "LOC"). Perpaps the best thing to compare is the size of the binaries on disk, but even that begs the question of "what's an executable"? Do ISPF panels, for example, count? -- John Eells IBM Poughkeepsie [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
