♂?，，

  When Feng Wen brought several bags of vegetables back home, she saw her son typing away on the computer. He then stopped and a dazzling array of colorful geometric lines appeared on the screen. The multicolored lines kept rotating on the screen, moving in a specific elliptical trajectory.

  When she walked behind Lin Hong, the lines on the screen suddenly disappeared and were replaced by a huge word "stone" that filled the entire screen, constantly changing colors in the order of red, green, yellow, and blue, cycling every few seconds.

  Lin Hong turned his head and said happily to her: "Mom, this is the program I wrote myself. What do you think? Does it look good?"

  "Using a computer so soon?" Feng Wan's face was full of surprise, if she hadn't seen it with her own eyes, she wouldn't have believed what Lin Hong said.

  Computers were a very advanced thing at that time, even for college students, without several years of study, they would not be able to use them.

  She herself had spent some time studying, but she was always confused. In her eyes, the difficulty of learning programming was simply more difficult than all other courses. She really couldn't understand why writing a few lines of code could draw such beautiful patterns on the computer.

  But her own son had already managed to come up with such a program in the nearly two hours she was away, which made it hard for her to believe.

  Although it's just a few lines of code on the screen, with no practical value at all, she knew that even though it was simple, it wasn't something that could be written offhand.

  Seeing her son's expectant eyes, Feng Wan gave him the answer he wanted most:

  "It's really beautiful. Mom, this computer has been placed here for almost two years, and I thought it was originally broken, but unexpectedly it can still be used to draw pictures." What she said is indeed the truth. When this computer first arrived at her place, she thought it was a broken machine for a long time, until one day when she visited a school's computer room, she realized that computers were originally like this, after booting up, there were only a few lines of text prompts, and nothing else."

  Lin Hong felt even more delighted after hearing his mother's words. After all, this was the first real program he had written with his own hands, and he had put a lot of thought into making the word "stone" appear in large font.

  After initial learning and exploration, he is now beginning to experience the joy of programming.

  Moreover, Lin Hong was no longer satisfied with simply following the example programs in the manual to print a few simple characters on the screen. He began to figure out how to use the various commands and functions provided in the manual to write his own desired functions.

  Just like the colorful lines and super large texts displayed on the monitor before, this is an example of a program that has no end, only examples of drawing single lines and changing text colors.

  Lin Hong typed out the code above verbatim and then began to tinker with it, making some changes to give it a bit of "freshness" and make it "different".

  So he increased the number of lines, which was not difficult to do and was easily achieved. However, when it came to enlarging the letters for output, things got a bit tricky. He re-read the manual but couldn't find a solution.

  He finally came up with a wild idea and solved the problem by drawing it. In other words, the oversized letters displayed on the monitor were actually "drawn" using the Basic graphics function, rather than being part of the system's native font library.

  One after another small program was born in Lin Hong's hands, he was completely absorbed in it and couldn't extricate himself, this feeling was totally different from the one brought by wireless.

  Exploring wireless is like going on an adventure, where things already exist and he digs with a treasure-hunting mentality, when he establishes a connection with another ham, he feels overjoyed, as if discovering a new treasure.

  But what brings him joy with computers is creation. This is a kind of perfect control, through programming, he can make the computer realize his own ideas according to his own will.

  To be honest, Lin Hong enjoyed this process more. Wireless telegraphy was also good, but the charm of computers seemed greater. He began to gradually understand why Lus's interest had slowly shifted towards computers.

  After dinner, Feng Wan took a bath and fell asleep soon. Today was really exhausting.

  Of course, she also reminded Lin Hong before going to bed and asked him to go to bed early.

  Lin Hong verbally agreed, but he remained in the study and didn't move a step.

  After dinner, he suddenly remembered that he had taken out several 3.5-inch square plastic cards from the cardboard box before, and after reading the manual, he knew that these cards were 5.25-inch floppy disks used to store data.

  He then inserted the floppy disk into the floppy disk drive, which was a small square box with two black panels printed with "disk_ii".

  Then, he types the command "pr#6" in the command prompt and presses Enter. This allows him to read data from the floppy disk into the computer's memory. This is because the floppy disk controller card is inserted into the sixth slot of the computer, and using this command starts the controller card, telling it to read data from the disk into the computer's memory and execute it.

  When Lin Hong pressed the Enter key, the screen suddenly turned black, and then a huge picture suddenly appeared, filling the entire monitor.

  This is a Western-style castle building, with a wide city gate, pointed roofs, blue sky and green grass. On the blue sky, a huge word "ulti_i" is displayed.

  Having been accustomed to screens with black backgrounds and green characters, Lin Hong was taken aback by the sudden appearance of such a vividly colored scene.

  "Is this a game?"

  He quickly reacted, after all, he had experienced arcade games and had a basic understanding of them.

  He realized that this should be a computer game. He had also heard of it from Lus before, and the other party had even written their own computer games.

  Lin Hong's spirit was suddenly lifted, and he followed the prompt to press the Enter key to enter the game. He almost intuitively started playing according to the simple prompts inside. It was a medieval-themed role-playing game developed by them.

  On his first night in Beijing, Lin Hong devoted himself to the first computer game he came across.
