We investigate multi-point algebraic geometric codes defined from curves related to the generalized Hermitian curve introduced by Bassa et al. Our main result is to find a basis of the Riemann-Roch space of a series of divisors, which can be used to construct multi-point codes explicitly. These codes turn out to have nice properties similar to those of Hermitian codes, for example, they are easy to describe, to encode and decode. It is shown that the duals are also such codes and an explicit formula is given. In particular, this formula enables one to calculate the parameters of these codes. Finally, we apply our results to obtain linear codes attaining new records on the parameters. A new record-giving [234, 141,≥ 59]-code over F27 is presented as one of the examples.
