The company that makes it also has a generator they use when they're contracted to make more code in their awful language. It's bad, the code has to be manually cleaned up and sometimes is delivered broken. Then they get the money on the support contract to fix their problems. (It's not their only product/service, but it's key to many of their services, a way of hooking customers.)

Their generator did not using the looping constructs, and several of their "senior" engineers actively discouraged it because "You can't be sure a loop will do what you want it to do." (Wish that weren't an actual quote.)

From my limited experience with "proprietary bullshit languages that only exist to hook customers", there's ways to mess up how loops work in the language. So maybe those senior engineers actually know what they're talking about.

I've seen "languages" that treat variables differently based on whether they have uppercase letters and underscores. Before I saw this in action, I believed the seniors telling me to "never use uppercase letters ever" were insane...
