INFORMATION SYSTEMS PROFESSIONAL

Z Series Mainframe

Worked mainframe for at least 28 years. 4 years Z/Linux under Z/VM at CFG in Binghamton. Loved it. Installed products under Z/Linux under Z/VM in virtual machines. Installed Z/VM 9 times. Installed numerous operating systems under Z/VM, including Linux, CMS, and Z/VSE. Am assembler programming expert. That helps with everything on mainframe. Installed many products under Z/VM. Wrote large, complex assembler programs to do printing from virtual machines under Z/VM. Love Z/VM. Great operating system. And Z/Linux has great value as a utilitarian operating system.

SPECIAL EMPHASIS ON ASSEMBLER PROGRAMMING AND Z/VM:

Am an expert assembler programmer

• Have been programming in assembler since the seventies. Total of many thousands of hours of assembler programming. Have written at least 50 macros. Have written at the operating system level for both VSE SVCs and Z/VM at the SIO start I/O level . Helped write a complete financial system set of programs for accounts receivable, accounts payable, payroll, general ledger, check printing. 100 assembler. Wrote a complete printer control system at the VM level in assembler. Wrote a complete CMS file backup/restore system in assembler. Still have all of the source for this. Can show the assembler program source as an example if so desired. Designed and built this entire CMS file backup/restore system from scratch. Later learned that there are commercial products which do exactly the same functions that my programs do. Know op codes on sight. Example : X'47F0A010' is an unconditional branch to 16 bytes past the address in register 10. Can do hexadecimal math instantly in my head. Can read a dump like other people read a newspaper. Expert debugger at the bit/bytes level. Expert at CICS internals and wrote thousands of lines of assembler code as application CICS coder. Experience with operating system control blocks, displacements, etc. Good at debugging Cobol programs, because I find the displacements, and can locate the exact Cobol statement which failed, and pinpoint the cause of failure data exception, operation exception, or whatever . Wrote a TCP/IP application for CFG in 2006 which extracted VSAM data on VSE and sent it across TCP/IP port 1500 on the mainframe to a listener which was running in AIX. My friend MIKE wrote the listener which ran on AIX. The 2 programs my assembler program running on VSE , and Mike's listener running on AIX ran for 42 hours straight on conversion weekend with zero errors and transferred all of Columbia Financial Group's VSAM insurance policy information to AIX. This policy information IS the company. It is all policy information going way back to the 1800's. This was a great and wonderful success.
• VM
• Did 9 complete Z/VM installations. From Z/VM 5.0 through Z/VM HPO through Z/VMXA Extended Architecture and Z/VM. Have worked with VM and CMS almost since 1981, while at the same time juggling all the other technologies, including AIX, SAN, and other programming languages.
• VSE 30 years VSE system programmer
• Installs, debugging, etc. CICS 20 years CICS system programmer and programmer
