这是一个数控系统的插补程序，实现逐点比较法和DDA算法的圆弧插补功能-This is a CNC system interpolation procedures, a case-by-point comparison to achieve law and the DDA circular interpolation algorithm functions

数控插补程序，直线插补和圆弧插补，1．直线插补：逐点比较法插补；2． 圆弧插补：DDA法插补第一、二象限的逆圆弧。 -NC interpolation procedures, linear interpolation and circular interpolation, 1. Linear interpolation : a case-by-point comparison interpolation; 2. Circular interpolation : DDA interpolati

我上传的是可以实现DDA法直线插补的VB源程序，-I uploaded the DDA method can achieve linear interpolation VB source,
