Yes, they exist. I worked with some about a decade ago. They ran on a single board computer with a flash memory card that emulated an IDE drive. They ran some 30+ year old industrial automation software written by someone who put everything into a single, messy, C file. It had what looked like a curses menu, but it did not use curses as a library. It also didn't use malloc. Source control consisted of sending the devs your .C file when you needed changes and getting a .C and a .EXE file in return.
I did automation by having all the computers source a batch file off a Novell Netware share and they'd reboot to have changes take effect.
So... yeah.
- Natsu 10y agoOh and how do I know it didn't use malloc()? Because we were running short on memory when using it. Why was that? Well, they had to store about one thousand 6-digit unit IDs. So they made the unit ID an int and created a UNIT_ID[1000000] array that I don't think was ever made it to 2% used.
