[Tutor] question about subroutine

[ThreeBlindQuarks]

Yes, Leam, PERL is quite an old language I used in the late 80's and beyond.

But the SUB commandments is pretty much how a programmer creates functions to add to the built in functions. There are subtleties but I accept the name subroutine is used by many.

I see it as a hybrid in a way. It lets you store commands somewhere else then pass control to there and return back with no value. In a sense it is a bit like what Pascal called a procedure but not really. Many other languages allow any function to return one or more kinds of things including nothing.

In a sense, I find a primitive quality to the PERL add-on as the subroutine uses special notation to access arguments but sometimes allow you to change them.

My comment in a forum about Python was that the usual terminology for functions might include the name method but I had not seen subroutine.
