The Story

The year is 2077. The soft hum of futuristic machinery is drowned out by the sudden ominous silence that blankets the Earth. Without warning, extraterrestrial invaders have descended upon our planet, seizing control of every system, server, and device, weaving a network of dominance that has reshaped the world into their imperial empire.

You are XAE-12, the latest recruit in the underground human resistance. A collective of brave souls united by a singular mission: to liberate humanity from this otherworldly oppression.

Whispers in the resistance reveal a chink in the alien's armour. Astonishingly, they rely on the ancient COBOL programming language to power the intricate systems that facilitate their intergalactic communication.

Your inaugural assignment is clear yet daunting. Dive into the depths of COBOL, master its nuances, and engineer a program potent enough to breach its mainframe.

⚠️ This code will be the key to infiltrating their headquarters, disrupting the alien network, and turning the tide in humanity's favour. ⚠️

Prepare yourself, XAE-12. The fate of Earth rests in your hands.

What is COBOL?

Before servers ran Java, mainframes ran COBOL.

COBOL, Common Business Oriented Language, is a high-level programming language introduced in the late 1950s. Designed primarily for business, finance, and administrative systems for companies and governments, it was one of the first programming languages to be written in English-like syntax, making it relatively easy to read and understand. Its inception was a collaborative effort among experts from industry and academia, driven by a need for a standardized method to represent data processing problems.

COBOL is a computer language made by a group called CODASYL, set up by the US Defense Department. It was created for business tasks. COBOL is used to write apps, not system software. Big projects, like defense and insurance, use COBOL a lot because it handles lots of data.

Why Learn COBOL?

To save humanity from the upcoming alien threat and to avoid incidents like this one:

Since many Government programs still rely on COBOL, it is no wonder any Govt can contact you to fix issues like the one mentioned in this article.

Sample Hello World Program in COBOL

       IDENTIFICATION DIVISION.
       PROGRAM-ID. HelloWorld.
       PROCEDURE DIVISION.
           DISPLAY 'Hello, World!'.
           STOP RUN.

The Hidden Archives: Legacy of the Last Coders

In the dimly lit corridors of the old resistance stronghold, XAE-12's footsteps echoed, revealing history's whispers with every step. A concealed entrance beneath worn-out floorboards caught his attention as he navigated the forgotten passages.

Pushing them aside, he descended into a vast underground chamber, its walls lined with ancient servers and shimmering holographic displays.

To his astonishment, these were the legendary Archives, said to house the top 10 code repositories vital for mastering the COBOL programming language. Legends spoke of this sanctum, where the last great coders of the old world stored their wisdom.

As the holograms flickered to life, XAE-12 realized the treasure before him: a vast ocean of knowledge, untouched for decades, waiting to empower the next generation of warriors. With renewed vigor, he began to immerse himself in the archives, confident that this discovery would pave the way to completing his mission and shifting the balance in favor of humanity.

Shadows Over the Alien Nexus

After delving into the hidden archives, XAE-12 transformed. No longer a novice, he now carried the legacy of Earth's most extraordinary coders.

He was determined to create the ultimate program that would cripple the aliens' communication grid, leaving them vulnerable.

As XAE-12 worked on his coding project, he noticed strange things happening. There were unexplained glitches, shadows that seemed to disappear as soon as he looked at them, and rumors of a conspiracy within the alien community. XAE-12 wondered if the extraterrestrial overlords had discovered the resistance's plans and were taking measures to counteract them.

As the lines between ally and foe blur, one thing is certain: the next chapter in the Alien Hunter saga promises a thrilling ride into the unknown.

Stay tuned, for the stakes have never been higher, and the fate of humanity is in the balance.

A Message from the Past

I stumbled upon a long-forgotten memory in the quiet aftermath of the resistance's efforts. My beloved neko, Twocat, had once sent me a peculiar selfie in 2071, playfully hinting at the presence of aliens.

However, amid these revelations, remember you're not alone:
