You're right, I removed the link. It's more like an improved version of your attempt. I managed to get every single piece of code using some mad Ctrl+F skills.
I came across that limit as well. I'm not sure if there's a limit for the keywords or there's a maximum line length, but I managed to make everything work fine by separating the constants in 3 different keyword sections. I searched for a while but I couldn't find a better solution.
