I once had this programming job that I thought was horrific.
Oil Field job.
The plc programs had been touched by a lot of ... let's just say, 'bless their heart' okies.
I eventually, became good at it (deciphering this monkey spaghetti) and it made me a better programmer for it.
I always wondered if somehow I could write a program to help me better understand the written plc program.
I.E. I once had a boss that would order the plc programs via huge FBD style pen and paper diagrams. It was actually kind of cool. Kind of peeved him off when I reduced this one huge one print down to one rung of logic using Boolean Algebra.
