Adenine (Haystack)

A blast from the past!

Adenine (also known as Haystack) is a programming language developed in the 1960s for use on the IBM System/360. It’s an assembly-like language that uses symbolic representation of machine code.

Here’s the “Hello World!” program in Adenine:

HLINK L
L OUT "Hello World!"
END
RUN

Let me break it down:

• HLINK L: This is a label declaration, which defines a symbol for the program. In this case, we’re defining a label called L.
• L OUT "Hello World!": This is an output statement that prints the string "Hello World!" to the console.
• END: This marks the end of the program.
• RUN: This executes the program.

To compile and run this code, you’d need access to an IBM System/360 or a simulator/emulator that supports Adenine. Otherwise, this is just a nostalgic exercise in programming history!
