Senior IT Specialist

IBM Corporation

Years in IT—

My first mainframe job—
Quality assurance testing for the Common Queue Server component of IMS, a premier transaction and hierarchical database management system.

Favorite mainframe memory—
Learning how to decipher console dumps, which at first glance is a jumble of numbers and capital letters arranged in blocks on a screen. Realizing that this intimidating scramble was actually something meaningful that I could decipher was like a light bulb illuminating. One aha moment went something like this: "Wow! C222 means that the code at offset 222 past the base register (or C) had control when problem xyz occurred!"

Favorite mainframe attribute—
One of the neatest attributes of mainframe is getting to work with High Level Assembly (HLASM) language, which allows you to work very close to the actual machine level. With this level of control, you can ensure maximum operational efficiency for your program, which typically just isn't possible with higher-level languages.
