What does this command do ?

[shlomyb]

Is there a meaning to
open(FILE,"<>file.txt) command.
I am asking because it seems that when I tried to use the open command again but instead <> I used < things get a little bit weird , meaning :
open (FILE,"<","file.txt")or die ("EXIT);
I got a return value 1 but not "EXIT" !

Can be?

-thanks.

A return value 1 means the file was opened successfully.

From perlopentut (

http://search.cpan.org/~nwclark/perl-5.8.7/pod/perlopentut.pod

)

If the filehandle was previously opened, it will be implicitly closed first.

So opening a filehandle twice in a row doesn't cause error; Perl closes the handle and then opens it again.

Thanks ,

Is there a meaning to the "<>" ?

Not sure about the "<>", but there is mention of reading and writing from the same source in the link that Kirsle provided.
