in thread How do I safely, portably extract one or more bytes from a string?
It relies on the fact that setting the $/ input separator to a numeric value reads in that number of bytes.
You need to set $/ to a reference to a number: $/=\1;. The example you gave sets the record separator to "1", which isn't quite the same thing :-)
