Hey I saw you seeded your random variables with the system clock! Do you remember my little election simulator? I did that too. I’m glad that it wasn’t just my crackhead idea and that there’s literally no better way to do it.

[@Vallee152]

@@ZemanTheMighty doesn't Minecraft get its seed from the system clock if you don't specify it?

[@ZemanTheMighty]

@@Vallee152 it does?! That’s a really cool fact

[@moltony]

​@@ZemanTheMightySeeding the random number generator with system time is actually very common

cobol is in a week!

Cobol is in a week! Wooho! I'm so happy for this information Cobol, just a week away, oh wow Can you believe it? Cobol, just in a week! It got here so fast.. Cobol. Just a week away!

Sometimes I feel like me and Truttle are the last COBOL coders of our generation. I love these videos

[@Truttle1]

I mean, if we’re in the same generation we might be the only 2 cobol programmers

[@ZemanTheMighty]

@@Truttle1You are probably in my generation +- 5 years so I count it

[@GeronKizan]

I remember learning COBOL and advanced COBOL in my last two years of college before I graduated in 2002. I thought it was gonna be useful since I thought I was gonna be working around the area (Davenport, Iowa) where there were a lot of machines that still used it, especially at John Deere

[@xenonbox9393]

How is it that whenever a Truttle1 video comes out the audio quality is always a gamble. Sometimes it's the quality of a good studio recording, sometimes it's like a soviet train station announcer.

[@sameer1321]

this video was very hard to watch due to my severe COBOL allergy, but I managed to watch it anyway Merry COBOL!!!

[@NickiRusin]

get well soon 🙏

[@IceMetalPunk]

In modern JavaScript, hoisting doesn't have to happen, if you just use const and let for all your variables -- which I absolutely do and 100% recommend any JS dev do. Even though I've been a JS dev for 21 years, hoisting has always been the dumbest feature of the language to me. (Speaking of 21 years... did you have to remind us that you were born after 2000, to make me feel ancient? 😔)

[@Ramonatho]

Cobol seems shockingly usable in a world full of functions with names so similar, like p=+p.

[@Blue-Maned_Hawk]

What?

[@moltony]

its a great day when Truttle1 uploads 🎉

[@vicr123]

Merry COBOL!!!

[@guyrocketram9698]

these videos are nice since my grandpa was actually a cobol coder! and when he told me that I actually knew what it was since I've seen your videos lol.

[@HexOverride]

OH MY GOD ITS BACK YOOOOOOOOOOOOOOOOO!!!!!!!!!!!!

[@retroboi128thegamedev]

Ancient mines from the days of COBOL placed across the board, The process of sweeping those mines started back in 1989 We are still sweeping mines to this day.

[@kellybmackenzie]

Your videos are always really funny and I love the effort you put into the little animations! You deserve a lot more views!

[@jdrukman]

In 1992 I got a job at Oracle. They had a weird technology called OCI that let you write database code intermixed with normal programming language statements. My job was to write example programs for OCI in various languages. Since I was the new kid on the block, I got all the obsolete languages, including COBOL. Even in the 90s COBOL was already old news. Just finding a compiler for a Sun workstation was a pain in the behind. There was no Internet so you couldn't look up where one might be. I did find one eventually on an FTP server somewhere. Then I had to teach myself COBOL, or at least enough to get the job done. I had managed to successfully block out all memory of what it looked like or how it worked. Then I watched your video. I will be sending you a bill from my psychiatrist, sorry about that.

[@n8chz]

I coded reversi (Othello) in Cobol, also that snake thing. That was a long time ago.

[@lalalifull]

In Japan, some bank accounts are managed by COBOL yet… Some old people say “traditions”.

[@BeconIsYeck]

glad to see you again during the holidays

[@vodam6970]

yay, my video idea got made! just because i tried making minesweeper in C

[@imperiallegionnaire8344]

Aparently my Grandfather knew Cobol. He apparently used it reorganize his bookstore.

[@jasperthegamemaster9237]

I have a song for these videos have a hairy scary COBOL and in case you weren't in fear have a hairy scary COBOL this year

Omg happy cobol to all

5:02 I'm just built different. I constantly ask for permission for even the smallest things and it's extremely difficult to apologise

[@jacobusburger]

At this point I’m convinced Truttle1 IS the last COBOL programmer. But seriously, how did you learn to do this?

[@zoltanpataki1307]

The way picture is defined makes sense when you read or write formatted data. PICTURE IS 9999/99/99 can be used for dates. when printing the value, the / will be printed automatically. Another example is Z vs 9. If you have 999, leading zeros will be printed if the number does not use all decimal places. ZZ9 will supress leading zeros by getting printed as spaces. You are not directly defining what the variable holds, but what should it look like. i.e. the picture of it.

[@cheesuschrist300]

yes!!! cobol

[@Scudmaster11]

How about SNOBOL now?

[@qwertzuioppel]

guess who deserves waaaay more attention because the content produced by that person is extremely entertai- yeah it's Truttle1

[@nnnArchive]

I’m working on using cosmos to make an OS in C#!

[@jayman1462]

MERRY COBOL!!!

[@lior_haddad]

3:38 python also does this... the only difference is that javascript's `var` keyword is old and deprecated, and allows you to use an uninitialized variable.

[@lior_haddad]

I will gladly accept javascript slander (js suc) but this one's rather unfounded

[@Mrcake0103]

Wait, no recursion? Are we _sure_ this thing’s actually Turing Complete? Like, how would you try to compute Ackerman’s function in COBOL?

[@Truttle1]

I’m pretty sure all recursive functions can be written iteratively so it should be possible

[@everynametaken]

It was made before stacks were a thing on most computers, so subroutines didn't allow recursion (nor was recursion really a thing for any language of the time). Technically there is a RECURSIVE keyword, but it doesn't appear to have caught on. Recursion isn't needed for Turing-completeness, once you get down to it it's basically replaceable with a GOTO.

[@raskr8137]

@@everynametaken That really speaks to how old the language is since stacks have become a common built-in processor feature way back in the 80s

[@jdrukman]

@@Truttle1 you are correct! One of the first things I learned in my high school algorithms class back in the mid 1980s. This served me well in my first job out of college programming 6502 assembly language. I had to convert spreadsheet equations in reverse Polish notation to infix notation. A C programmer I worked with recommended I use a recursive function.. I told him "to hell with that. I'm not writing recursion in assembly language." Luckily, I remembered my high school class and even better, I still had my textbook which had a description of how you do this exact conversion without using recursion. (The answer is two stacks). I was so pleased when I actually got it to assemble and run correctly! 30+ years later, this is still one of the standout moments of my career.
