 adxwrb=10 : # Recommended value

For performance reasons, you can buffer database write operations by using a dedicated instruction called [Writeb](../4gl/writeb.md). When this instruction is used, the write operations are grouped in a buffer and written when the buffer is full, that is when the number of delayed write operation reaches the value of `adxwrb`. The behavior of [Writeb](../4gl/writeb.md) is different from instruction [Write](../4gl/write.md) because the errors that might happen during insertion are returned only when the write buffer is flushed.

A modification of the adxwrb variable triggers an error if lines are still present in the write buffers. It is therefore important to execute a Flush or a Rollback before modifying it.
