All, Ted,,,I am an ex-VM, VM/SP1 thru z/VM. MVS -- OS/VS2 thru z/OS 1.6. I was once a big VM bigot working as an internals VM System Programmer for 10+ years before jumping into MVS because of the availability of work. I enjoy both systems and love Linux too. Every Operating system and programming languages have pros-cons. Your experience tells you which one is best for you to write in and use based on functionality and performance.
I also am very familiar with the VM and Linux link. They are like kissing cousins , amazing how alike. Yes I have worked in software development also and at the present time do with Identity Management. So I am seeing the security issues many fold..working with a product using RACF, ACF2 and Top-Secret. Once final thought, the mainframe knowledge is rapidly disappearing in a lot of old mainline mainframe shops. Who will take of them when us old 'dinosaurs' retire or whatever. Outsourcing is not always a good solution.

IBM did not write LINUX, in any way shape or form. It was originally written, in the early 1990's, by a bunch of PFCSK's. I believe it was written for the INTEL platform first, but I could be wrong (and, not blowing smoke). The initial person was a Scandinavian named Linus Torvalds. There is a 15-company consortium that works on changes to the source streams for the various platforms. IBM is a member. IBM does not send you a distribution, rather they recommend which one(sy) to use. >If LINUX is written in C then whose version of C is it? DIGNUS/SAS >(?)/ or ? it certainly can't be IBM's (at least the one they released >to to the general public). Does it matter? There is a gcc compiler that comes with most distributions. IBM's compiler may or may not work -- I've never used it for LINUX. >Its typical of people like you to end the discussion with an ignore. There is a reason for that! >I tend to read everybody's opinion then form a judgement Is this judgement based on facts? IBM did not set the standard for LINUX. They are following it, just like they do for JAVA, APACHE, and other open products. They were 'late' jumping on the LINUX band-wagon. I had a working Caldera distribution on my IBM laptop, long before IBM acknowledged it. I don't believe it runs on a MAC, yet. But, it runs on WINTEL, SOLARIS, AIX boxes, and (of course zBOX), embedded systems and many more. IBM is not setting a trend. Rather they are following one. Before you pass judgement, try reading: http://en.wikipedia.org/wiki/LINUX But, this is not an IBM boondoggle. Rather, it's an attempt to expand what can run on a z. There are a lot of strong (most seem to be ex-VM'rs) team of LINUX supporters within IBM who are trying to bring the OS to the great unwashed. The two biggest are Alan Atmark (US) and Jim Elliot (Canada). And, I tend to believe them before I will even listen to you. Rather than painting LINUX with the same (out-dated) brush that you are painting MVS with, why don't you do some research and verify your facts. IBM has changed! You have not!!! - Too busy driving to stop for gas! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
