LINE appears to refer to a label, so you could look for a labeled bareblock, 'LINE: {...}' enclosing this line of code.

The effect of while (($line =~ /abcd/o) .. ($line =~ /def/0)) is to skip back to the label (presumably to read another $line) when $line has matched 'abcd' but not yet matched 'def'. I have no idea what the '0' does, but it might be a typo for 'o'.

This construction will fail if abcd-def pairs can nest.
