Thanks Tim.
I can't imagine being comfortable writing new code, at least, for a compiler
that has not been updated in 35 years, but maybe that's just me. 🙂
Now that we know what languages are still supported, I am still curious if
anyone out there is actually still using them, and if so, why.
1. I'm pretty sure there are users of those compilers, this is the only
reason to keep them under support.
2. I guess the users do not create new applications from scratch rather
they maintain and update existing applications. Is it safe to use so old
compiler? It is safe to use *supported* compiler. Age has no big meaning
here, what would you say for 7 years old, but unsupported compiler?
BTW: As a mainframe bigot I sometimes am forced to explain why so old
things are still in use. Yes, z14 or z15 is veeeeeery old. As old as
z/OS 2.4, or DB2. It is hard job, because usually nobody want to hear
answers, but one of my favorite is the wheel. Wheel is quite old idea,
but still in common use. They say M$ introduced a car without wheels or
the the wheels are enhanced - square...
Last, but not least: some 20 years old COBOL code is not obsoleted by
changes in the OS/compiler/whatever, but code on Windows *had* to be
rewritten several times during this period. Dot net? It was so modern
just few years ago and now is obsolete. Note: that means programming
effort just to upgrade system, without any application (business logic)
changes.
