BTW, there is no language named ADA.

We should cut people some slack about this, especially considering that the language itself is case insensitive :P

I'm not sure what actually triggers the confusion about this, but it is Ada, not ADA. It's not an acronym, I'm curious about the origin of the incorrect all caps version, but it seems like there's a forgotten historical reason for this.

Ada came out of the DOD so assuming it's an all-caps acronym makes a lot of sense. ;)

Jean Ichbiah might have bristled at such an assertion. (He called his language "Green".) But, renamed, Ada was heavily promoted by the DoD.
