Ten lines of code that changed my world

    The BASIC print+goto loop might have been my first ever program too (in the 80s) but one thing for sure for me: it was definitely not “Hello, World”. I and others filled the screen with any number of silly things, random words, jokes and juvenile phrases, whatever, but for some reason, “Hello, World!” was a C thing, and I remember seeing it for the first time in a C class in high school, and then much more often in college.

    I have memories of ‘poke’ as well. On the Atari 800 you could poke memory to change the keystroke repeat rate and delay before repeat started, so obviously we would turn down the delay to zero and turn up the repeat to max (it was maybe 60 characters per second), so anyone trying to type couldn’t hit the keys quickly enough to avoid repeating. You’d have to power-cycle the machine to fix it, so it was hilarious to 11 year old me.

    Similar to his description of ‘poke’, but different mechanism - using debug.com on an IBM PC jr to edit the Ultimate III save files, and give myself maximum money and lives.

    Good times!

      I started with

        10 FOR I = 1 TO 10
        20 PRINT I, SQRT(I)
        30 NEXT I
      
      and struggled to type this without errors into computers in department stores. I must have read this code somewhere and needed to see it working for myself.

        I remember discovering ? as a shortcut for PRINT on the C64. That was when software development as a profession really started looking like a good choice to young me.
