Here in the States, I’m dealing with a company’s ERP class software, written in Basic, developed in 1970. At least a thousand people use this software. My friends tell me that, first, this is a common thing; second, there are specific companies that specialize in supporting anything old; third, there are special products that emulate terminal operation in response to user actions in a pleasant graphical interface. That is, you move a slider, and somewhere it simulates pressing keys on a keyboard.
An interesting experience.
