map?

[Mallik]

I couldn't understand the functionality of map in PERL. Is there anybody to
help me?

Thanks,
Mallik.

[Ohad Ohad]

perldoc map
perldoc grep

They both have very semilar functionality of creating a new array from
existing one.

Those need a '-f' to work....

perldoc -f map
perldoc -f grep

Did you read the docs? What were you looking at that you didn't
understand? What have you tried, where did it fail or what confused you?

If you didn't read the docs, you can always access a built-in function's
documentation by perldoc -f <function> ...

This is the second open ended question you have posted, a third willl
indicate a pattern that may not get much response...

p.s. Either Perl or perl never PERL, perldoc -q '"Perl"'

Did you need understanding HOW to use it, or what you'd use it FOR? If
you need help with HOW to use it, I'd ask that you first read the docs

perldoc -f map

and then show us code you've tried with it. If you need help with what
you use it FOR, I can give you some advice and some pointers.

In brief, map returns a list represneting the mapping of a function onto all
elements of a list. The original list may or may not be affected by the
function, depending on the syntax by which its membes are addressed.
