OK thanks

the reason for me to output as an octal number it is an habit when
talking about perms...
i'll look at the C library to output that the correct way.

> num = "775".to_i(8)
> dec = num.to_s             #> "509"
> oct = num.to_s(8)          #> "775"

i've allready a way to output my number as an octal "775" BUT i'll
like having better "0775" because in the C language the first 0 means
octal and i ask for xhen input .
