I have never used octal numbers in my code nor come across any code that used it. I bet you have. According to the standard, numeric literals which start with zero are octal. This includes, trivially, 0. Every time you have used or seen a literal zero, this has been octal. Strange but true.
If you are making child support payments in Texas, the law generally requires you to do so until your child turns 18, which is the age that marks adulthood in the state, or when he graduates from high school -- whichever comes later.
A: Any Georgia court order issued after 1993 establishing child support amounts should provide for support to continue until the child turns 18. If the child is still in high school past the age of 18, support will continue until the child finishes high school or reaches the age of 20, whichever occurs first. If your court order was issued prior to 1993 or in a state other than Georgia, support is due as indicated in the court order. Generally, Georgia court orders entered prior to 1993 cannot be modified to extend support past the child's 18th birthday.
