Yes, but aside from perhaps small utility programs with minimal
demands on system resources, such long lived programs are rarely
long-lived in isolation from their environment.  So in many of those
COBOL cases those applications were still running within the
environments in which they were written and designed for and on the
same systems.

In the Python world, that would be equivalent to keeping the platform
(and installed Python interpreter) along with the code.  Hey, and it
would be much harder to lose the source too!

True, but for this specific issue (division) I'll certainly admit that
when writing "x/y", the reason I expect truncation of that (and my
brain actually thinks about it) is because of my C background.  I'm
not thinking just "division" when I write it, I'm thinking "integer
