This function returns the numeric ASCII value of the first character of EXPR . If EXPR is omitted, it uses $_ . The return value is always unsigned. If you want a signed value, use unpack('c', EXPR ) . If you want all the characters of the string converted to a list of numbers, use unpack('C*', EXPR ) instead.
