I assume PERL:
if you have a collection with (key,value) pairs
you can iterate through all keys and get the value...

in english:
for each key in collection get value...

that is the idea of the keyword
for each

it does that in visual basic too

  
For Each TH in ObjCollection
  TH.MoveMe()
Next TH

that would call the MoveMe() method in all of the objects in ObjCollection.

Actually, you can do it in C++ too, with the for_each algorithm on the STL container classes.

C# Supports it also, if anyone cares.

Actually I meant in C++. I dont understand....
It gave something like this:
for each function()
{
...
}

Well, that''s not actually valid C++, so I think it was probably just trying to give you pseudocode or something.
