You don't need to split into an array to access positions in a string by index, you can use substr (or index to search for the indices of "-", or even a regex and pos). Also, you can output a new file with only the characters you want instead of manipulating a large string.

Show us some of your code and we can help you with that...

(I dimly remember seeing a similar question on PerlMonks recently... have you Googled your question?)
