Code brackets with unlimited read lines

I’m using chatGPT to code for me and it’s fairly useful if your code is under 150 lines but when it exceeds this, ChatGPT seems to not read the entire code or ignore part of your request. I’d like it if there was an attach or insert code function where chatgpt parses each and every line of code while in that code box and doesn’t count the code box toward the character limit. I believe this would be extremely helpful for developers to troubleshoot issues and check for errors or duplicate code
