I want to assign the value say: 'ABC' 0x01 0x02 0x00 0x00 0x00 0x09 to a nine byte string. I assume I can get there, but question one is what is the best (most efficient) way to do that?

Question two is why doesn't this work? 
my $var = pack('a3CCx3C','ABC',01,02,09);

That produces: 
Illegal octal digit '9' at ./myscript line 10, at end of line

I can change 09 to 19 or 99, then it will "work" (meaning it assigns that value, which isn't the value that I want). What is wrong with 09?
