I'm very new to the J programming language, so I got interested in array programming languages and decided to give it a go. Unfortunately, It's a very niche language, meaning that there aren't many learning resources available. For that reason, I haven't figured out how to get user input in J, I'm making a simple program where the program asks the user for a name and greets them.
I tried asking ChatGPT for the solution, However, It didn't work.
I'll still show the code it told me: insertVariableNameHere =: 1!:1]0
I also tried searching for it, but it gave me results on java, jquery, javascript, and other unrelated languages.
ChatGPT is close, but in terse languages like J, close is not good enough. It does use 1!:1 which is the 'read from files' foreign conjunction, but it needs to have the argument 1 and not 0.
read=: 1!:1 NB. read becomes a verb to read from file
variable=: read 1 NB. 1 designates keyboard as the source to be read
1 2 3 4 NB. indented waiting for input
variable NB. Now contains what you entered.
1 2 3 4
Nothing that you are asking here is obvious or dumb. There is a lot of information about J in the J wiki and a really good place to start is here: https://code.jsoftware.com/wiki/For_New_Users or for more learning materials: https://code.jsoftware.com/wiki/Books
If you move off of jconsole onto either JQt or JHS environments you also get the benefit of the J labs which are interactive tutorials. Enjoy your journey with J.
