This is what I think Question 1 could be.. I have no idea to be honest. sub CheckJumpDestination { my($jump_destination) = @_; if (exists($jump_destination)) { print STDOUT "Jump destination $jump_destination has already been received.\n"; } else { # Your code here. } }	[reply]

Yeah I learnt a little about the exists function in the book and the examples it gave made me think it would be ideal for question 1, but I was not entirely sure if I was on the right track. I understand that exists is used to search a file or variable for values.	[reply]
