Re: split a line by control ^D character

[eyepopslikeamosquito]

The problem is that the chr(4) inside your /chr(4)/ regex is not being interpreted as a function call; rather it is being interpreted literally, with the parens in chr(4) being interpreted as regex metacharacters to capture the 4 in a matching chr4, for example!

There are a number of ways to fix this, for example:

@LineDetails = split /\04/, $line;    # ... or
@LineDetails = split chr(4), $line;
