What improved technology? You mean OOP? Well perl does OOP.
Are you talking about inheritance? Perl does inheritance.
It is high level languages like perl, python, tcl/tk (and to some small extent 
shell
languages) which are the driving force of the internet.

If you mean that you expect a high level language to write the code for you, 
perl,
python, tcl do that also, to a degree. For example the split() function in 
perl; takes
as arguments, a string, and a delimeter and returns a list (array) of all the 
items in
the string.
$test_str = 'mike:bob:bill:jim';
@test_ary = split($test_str, /\:/);
Just think how much code you would need to write in RPG, or the all powerful c 
just to
beable to do this same thing.

Or do you mean that a high level language is one that catches your errors and 
corrects
them, well using the -w option perl can even help there.

Perhaps you should do a little research.

Yes, thats exactly what perl, python, basic, .... blah blah blah, do fo you. 
They
provide the menial code so us programmers can play quake.
