https://www.artinsolutions.com/competencies/mediationzone%C2... says "Business logic of these agents is defined in APL – Application Definition Language, which is based on Java language." which doesn't sound like the APL I know.

https://careers.digitalroute.com/jobs/98847-implementation-c... has a code sample (https://stuffthatiliketoshare.files.wordpress.com/2014/07/no...) which does not look like APL at all.

It seems like they're very successful from their website. What was bad about it?

I would personally love to have a built-in APL scripting language for interacting with data.

Based on the other comment, it looks like it's another language that happens to shorten down to APL in name rather than APL "A Programming Language". It looks like some internal Java derivative language which sounds like could be rather painful if not done well.

Ohhh gotcha. Yeah, I'd hate to use just a crappy Java. I think either Salesforce or SAP does something similar.
