A bit longer than 2 decades ago, I got MicroFocus NetExpress to use DirectX, just for fun. Never did anything relevant with it, but it was possible (on Windows)

In that vein, I'd find it interesting to see a neural network implemented in COBOL. But I won't hold my breath :)

Really? COBOL is younger than neural network algorithms and seems like a prime language to write neural networks!

The first artificial neural network was invented in 1958 by psychologist Frank Rosenblatt. Called Perceptron, it was intended to model how the human brain processed visual data and learned to recognize objects. Other researchers have since used similar ANNs to study human cognition. [0]

COBOL is a high-level programming language first developed by the CODASYL Committee (Conference on Data Systems Languages) in 1960. [1]

You aren’t talking about libSDL, do you?

:)

I most definitely am. http://libsdl.org/

The need is strong.
