Do we still use some outdated languages ?

Clarifications

In effect, any language that is STILL in use just tends to prove that it is a stolid platform that has not required to be updated.

COBOL is particularly suited to older computers.

PASCAL is IMHO an excellent language for anyone 'learning' to code - it sat very well with me before I graduated to C++. If it hadn't been for PASCAL I'd not have passed my Post-Graduate course.

Just because something is old, doesn't mean it is no longer valid - LOOK AT MOST OF THE TR PEERS !! :D

And I just only recently touched on XSL.

Nice thing about HLL is that you can pretty much drop one and pick up another fairly easily, as most of them are very similar.

languages have a place as you use different languages for different situations and uses.

And the answer is yes.
Perl is dynamically typed, all of your chosen three are static. Fortran and Cobol are specialist languages, yours are general. Pascal is just as powerful as C, but it's strongly typed, so makes it easier to write better code. Outdated is a market description, not a technical one. Proof is easy to come by just look at VB6. Popular beyond credibility, but technically a total POS.

I can do Fortran, the place I worked at had something in the region of a 100 vax machines running a twenty to thirty year investment in domain specific business critical inhouse code. Imagine the cost of replacing that compared to teaching you Fortran, which wouldn't take long at all if you are even vaguely competent...

Don't knock it, you could get a decent paying job in Fotran, Perl or Cobol. Pascal is still highly thought of as first langauge for teaching procedural programming.
I've never seen a better one for doing it.
