Operating system for DOS
Operating system for DOS
It appears your argument doesn't relate to the topic the other person is addressing. Call centers typically don't use DOS, and most major organizations depend on it only for older systems—such as certain health and power companies. Even in those cases, their legacy setups often run on Unix, OS/2, Sun, or proprietary operating systems.
The inquiry focused on understanding why DOS programs remained active despite limited visibility. The discussion centered more on broader system behavior than specific app implementations.
I just learned about a German insurance firm that stores its data on DOS. I’m eager to find out the programming language they use.
A Commodore 64 serves as the primary machine in a Polish auto shop. It has been used to power an HVAC system across 19 schools for more than three decades. Even though it's not widely used today, it still holds value. It's worth noting that while many DOS-based programs rely on command-line interfaces, this doesn't automatically mean they're DOS applications. UNIX and Linux were built around command lines, but they differ significantly from DOS environments. Some tools may appear to run in a virtual machine, and it's interesting to see Intel still developing network drivers for MS-DOS, with the latest release dated June 19, 2017.
My bank relied on DOS for a long time. They had already purchased it, so changing it would cost a lot of money. It would require thousands of Windows copies, and if it's not broken... don't try to fix it. Another trend to consider is "why do companies still use Pentiums and Core 2s?" Because upgrading them is expensive. If those parts still function, avoid replacing them.
