Optional interpreter visualization of tape
CLI or IDE displays outputs
No graphical UI by default
Some online interpreters provide colorized loops
State Management
Memory tape holds current program state
Pointer tracks active cell
Loops control conditional execution
Program input/output modifies tape or console
No external state management needed
Data Management
Input via , command
Output via . command
All data resides in tape cells
Tape size can be adjusted to hold more data
No built-in persistence beyond execution
