Pity it does not support Basic or CBasic etc.

If you scroll all the way to the bottom of the front page, you can see
they support AI generation for 62 programming languages. Unfortunately,
Basic and CBasic are not on the list, but VB.Net, VB6, VBA, and VBScript
are supported.

Some of the programming languages are completely unknown to me, like
Julia, Kotlin, Scala, Clojure, Dart, Elixer, Elm, Erlang, Haskell, and Haxe.

The Assembly language generator assumes the only assembly language in
the world is X86-64.

Popular programming languages like C, C++, Java, Javascript, Ada,
Fortran, Python, and Rust are supported.

I asked it to create a program that performs a credit card Mod 10 check
digit validation using the Luhn algorithm, which is described in a
Wikipedia article:

https://en.wikipedia.org/wiki/Luhn_algorithm

The check digit algorithm is intended to detect digit transposition or substitution when a credit card number is manually typed.

In this case it generated a "MAIN-LOGIC" paragraph instead of
"MAIN-PARA", but the generated COBOL looked pretty reasonable. I
compiled it with GnuCOBOL 3.2 and it appeared to execute correctly, and
I also tested it with different "card numbers" generated with difference
check digit values.

MOVE WS-TABLE-DIGITS(WS-I) TO WS-DIGIT

IF FUNCTION MOD(WS-I, 2) = 1
COMPUTE WS-DOUBLED = WS-DIGIT * 2
IF WS-DOUBLED > 9
COMPUTE WS-DOUBLED = WS-DOUBLED - 9
END-IF
ADD WS-DOUBLED TO WS-SUM
ELSE
ADD WS-DIGIT TO WS-SUM
END-IF
END-PERFORM.

DISPLAY-RESULT.
COMPUTE WS-MOD-RESULT = FUNCTION MOD(WS-SUM, 10)
IF WS-MOD-RESULT = 0
DISPLAY "CREDIT CARD NUMBER IS VALID."
ELSE
DISPLAY "CREDIT CARD NUMBER IS INVALID."
END-IF.

Of course, this means the pointy-haired bosses will want all the new
programs written by AI bots, so they can pay us less.

Nearly every chatbot can already convert most programs from
one language into another, although the quality might be worse
for languages that are less common. So, if you want to convert
from a language called "Basic" to a language called "CBasic",
I'd recommend to try it with some chatbot.

It was the style of the naming convention that caught my eye, Mr Trembley,

resulted.

I have heard of Haskell, but not the rest. ;)

Julia is high level language primarily used for scientific computing.
Dynamic typed but AOT compiled to native. The language you want if
Python is too slow and Fortran is too cumbersome. :-)

Kotlin is a JVM language. Consider it how Java would have looked like
if Java had been invented in the 2010's instead of 1990's.
Widely used in Android development, but also some server side.

Scala is also a JVM language. A language based on the "more features
is better" philosophy. It is used some places for advanced stuff.
Including some widely used frameworks: Akka, Spark and the core of Kafka.

Clojure is a Lisp dialect for JVM. Pretty hot 15 years ago. Rarely
used in real life.

Dart is Google not so successful attempt to create what MS
successfully did with TypeScript. A better language than
JavaScript transpiled to JavaScript.

Erlang is a weird language invented by Ericsson a long time
ago for HA applications. Still used in telecom and a few
very widely used applications including RabbitMQ.

Elixir is a higher level language than Erlang but running
on same platform. Hot but not widely used.

Haskell is (together with OCaml) one of those finer
FP languages taught at finer CS studies. And almost
unused in the real world.

Elm and Haxe I don't know.

I think before Haskell, there were many different functional
languages like Miranda or Hope, and then Haskell became /the/
mainstream/default functional language. It /is/ used for at
least one application of high practical value: pandoc.
