IBM System/360 Assembly language. Developer Hiring Guide

IBM System/360 Assembly language, introduced in the 1960s, is a low-level programming language used for direct hardware manipulation on IBM's System/360 mainframe computers. It was designed to provide programmers with a means of controlling every aspect of the system's operation. The language is characterized by its use of mnemonic codes and symbolic addresses, making it more human-readable than machine code. Despite its age, it remains relevant in modern mainframe environments due to its efficiency and control capabilities. Information sourced from IBM's official documentation and historical records.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with IBM System/360 Assembly language..

What does this simple Assembly language code do?
START 0
LOAD A
STORE B
END
This code loads the value from memory location 'A' into the accumulator and then stores the value from the accumulator into memory location 'B'.
What does this Assembly language code do?
START 0
LOAD A
ADD B
STORE C
END
This code loads the value from memory location 'A' into the accumulator, adds the value from memory location 'B' to the accumulator, and then stores the result in memory location 'C'.
What does this Assembly language code do that manipulates an array?
START 0
LOAD A(1)
ADD B(1)
STORE C(1)
END
This code loads the first element of array 'A' into the accumulator, adds the first element of array 'B' to the accumulator, and then stores the result in the first element of array 'C'.
What does this Assembly language code do that involves threading or concurrency?
START 0
LOAD A
START 1
LOAD B
ADD A
STORE C
END
This code starts two threads. The first thread loads the value from memory location 'A' into the accumulator. The second thread loads the value from memory location 'B' into the accumulator, adds the value from memory location 'A' to the accumulator, and then stores the result in memory location 'C'.
