in thread Extracting Data from a second line

So, what is the answer then? When reading DATA, do we continue to manually count the characters and use that? Or do we use a number that we know will be sufficient (1000000 or something similar) but is guaranteed too big? These are more rhetorical questions than anything. I would just like a way to find the size of DATA, programmatically.

If you wish to know the size of DATA, in characters, use the following. It will work on with all line terminators and will all encodings. `$size_of_DATA = read(DATA, $buf='', -s DATA);` [download] It's safe to use `-s FILE` because the number of characters in a file should never be bigger than the number of bytes in a file.
