My Name is Greg,
20 Years as an IBM MVS/CICS/OS390 and as I understand it, I am also qualified for the "new" name Z/OS systems programmer. My Mainframe experience is assembler language. I wrote a lot of OS exit routines to handle security, special devices, non compliant hardware. VTAM exits to handle non compliant software.
I am proficient in IBM Assembler, COBOL, FORTRAN, and other lesser known languages.
The first "micro computer" I was introduced to was the Apple II. It had this program called "VisiCalc". My professor said this was going to revolutionize the way we manage business. This was 1983. and he was correct. I am a 1984 graduate of OIT, now Known as DeVry Institute of Technology.
I wish I had started a VisiCalc education business then, Hind sight is 20 20.
Always learning and want to know the gory insides of these damn malware and virus infections.
