Having worked on the PL/1 and Assembler that formed the core accounting systems of a bank: yes.
Not only did I have source control I had flow diagrams of the entire system for all points in the chain. My code reviews had me doing line-by-line justifications. I wrote tests.
Just because the technology and practitioners are old it doesn't mean they don't know what they're doing.
Generally they invented whatever "you" are reinventing the first time around.
