  While BASIC++ defaults to an Immediate Mode REPL, it also natively supports a Deferred Mode workflow (similar to 
QBASIC or modern IDEs) via the built-in screen editor. In Deferred Mode, statements are not evaluated or executed 
line-by-line as they are typed. Instead, you write your entire program within a text buffer offline. Once the program 
is fully written, it is passed to the host engine in a single batch for execution.
  
  To invoke Deferred Mode, launch the interpreter with the --edlin (or --edit) flag:
  
  > basicpp-console.exe --edlin
  
  Once inside the editor, you may use the x command to execute the entire buffer as a BASIC++ program.
