let's say I'm reading the following line form a text file
Hello\nWorld
which is equivalent to:
my $Message = 'Hello\nWorld';
I want to print this string and I want PERL to interpret the \n as a line break.
print($Message);
gives
Hello\nWorld
which is what I would expect
print("$Message");
also gives
Hello\nWorld
I was hopping that "" would cause the string to be interpreted but no...?
I tried
print(eval{"$Message"});
same result
Of-course I could split my string and print each section on a newline myself but it should be possible to have perl interpret this string.
Thanks for your help.
