Because I parse it as: an octal escape sequence can be \d, or \dd or > \ddd; and the result is a byte value.
Exactly. But for the parser the "byte value" is irrelevant, that part is semantics (and checked later). Syntactically you write an octal number with upto three digits. If you want to write a two digit octal number you can not continue with another ocatal digit. In C you could do "...\77" "7" and have it concat the literals. In config files (without concatenation) you need some other trick. Martin
