• What is your job title?
Although I retired last year, I continue working as an Assembler, JCL, and COBOL Developer and QA.
In addition to creating programs and maintaining production processes, I have translated programs from Assembler to COBOL to run on Microfocus (I have my doubts… can 50 ponies do the work of an elephant?)
• How long have you been working with mainframes?
Since 1986, when I completed the first of several mainframe programming courses, I have worked at IBM and at the main banks and telcos in Argentina.
• What mainframe technology are you passionate about or would you like to learn more about?
Where file volumes were very large, on the order of tens of millions of records, I had several successes optimizing programs and batch processes to reduce execution times and resource consumption.
Researched and implemented invoicing programs in COBOL using Report Writer.
I took some courses and conducted tests in Python, SAS, Easytrieve, and Focus.
I have also researched Number Theory, and participated in the IBM 3090 Competition with an Assembler Batch program to discover amicable and perfect numbers by outputting a list, in 3 minutes this program could test a million numbers.
I first tested some COBOL complex statements on a laptop using OpenCOBOLIDE and I'd like to learn more about modern IDEs like RDZ and others (ZOWE?).
• Share a fun fact about yourself or your favorite hobby.
I like Italian cuisine, electronics, walking, cycling and motorcycles. I've owned British, Italian, and Japanese motorcycles.
In 2011 when I went to visit my brother-in-law in Miami and rented a Harley Nightster for a day; standing still it feels as heavy as a hippopotamus, but walking it's like a kitten...
