It was the process of letting a computer solve a certain problem on behalf of a certain calculation system, and making the calculation system operate according to the calculation method, and finally obtain the corresponding result. In order for the computer to understand human intentions, humans needed to tell the computer the ideas, methods, and means to solve the problem in a form that the computer could understand. The process of communication between humans and the computing system was programming. The programming here was not necessarily for computer programs. Any system with logical computing power could be considered programming. The programming class was a course that taught knowledge and skills related to programming. In the programming class, students would learn the basic grammar of programming languages (such as data types, operators, branches, and cycles, etc.), use the programming language to implement basic data structures (such as sequence tables, linked lists, etc.), improve their programming thinking and problem solving skills by brushing algorithm questions, and carry out practical projects. For children's programming, they would use more interesting and child-friendly methods, such as using beautiful game screens, cute animated characters, and a standardized programming interface. They would let children learn to break down complex problems into simple steps and write code to execute these steps, thereby cultivating logical thinking, computational thinking, and creative thinking.

Numerical-control programming was one of the main contents of the preparation stage of Numerical-control processing. The process was the whole process from the part drawings to obtaining the Numerical-control processing program. This included analyzing the part drawings, determining the processing process, calculating the tool path to obtain the tool location data, writing the numerical control processing program, making the control medium, checking the program, and the first piece of trial cutting. There were two methods of programming for the numerical control processing, manual programming and automatic programming. The various stages of manual programming were completed manually. The programmer used general calculation tools to calculate the tool trajectory and compile instructions manually through trigonometric-function calculation. This method was relatively simple, easy to master, and had great adaptability. It was suitable for non-mold processing parts. The steps included manually completing the numerical control process of the parts, analyzing the parts drawings, making process decisions, and determining the processing route. In programming, there was also the special function of the user macro program. There were some differences between the user macro program and the normal program. In the user macro program, variables could be used and assigned values. The variables could be calculated, and the program could jump. However, the normal program could only specify a constant, and the constant could not be calculated. The program could only be executed in sequence and could not jump. The function was fixed. The format of the macro program itself was the same as that of the subprogram. It could use normal, variable, calculation, and control commands. For example, in some engineering application scenarios, such as the calculation of circular arc evenly distributed holes, oval processing, etc., the use of macro programs could improve the efficiency of manual programming.

" Program " was the short form of programming. The essence of programming was to let a computer solve a problem on its behalf. This process required a specific calculation method for the calculation system to operate in this way to obtain results. In order to achieve this goal, humans had to transform the ideas, methods, and means of solving problems into a form that the computer could understand, so that the computer could work step by step according to the instructions to complete specific tasks. The process of communication between humans and machines was programming. In addition, programming could also be seen as designing a " controllable system " with logical flow. Moreover, programming was not necessarily limited to computer programs. The operations related to systems with logical computing capabilities could also be considered programming.
