is not very smart. Microsoft needs to take a couple of pages out of
IBM’s playbook. (I’m an IBM mainframe systems programmer)
In the Mainframe world, there are also DLLs (e.g. SYS1.LINKLIB) However
the BIG difference is IBM doesn’t allow you to modify their DLLs.
If you want to call services in z/OS (latest version of MVS) you make use
of IBM’s many Exit points, and system service macros which provide
developers with a standard interface to the OS and the machine itself.

IBM also has a Change Management Database called SMP/E (SystemManagementProgram/Extended)
It consists of a Database of all changes and versions of all elements of
the operating system. Any developer who wants their software to run
on z/OS is strongly urged to make use of SMP/E.

If Microsoft would adopt these principles, it would make Windows a lot
less prone to bad code, malware, and viruses.

I’ve been in .dll hell many times.
