How to Play Playbox BASIC
Quick start
Enter the edit screen with START and enter a short line such as "10 PRINT" from the keyboard or the on-screen character table. It is assumed that A confirms a character or command, and B deletes a character or goes back. After entering a few lines, select RUN to execute, and if an error occurs, return to the displayed line number and correct it. At first, try using the screen display and simple addition.
Controls

Playbox BASIC — About this game
"Playbox BASIC" is a programming environment for entering BASIC language commands on Famicom to create and execute programs. Try out short calculations and simple games by combining line numbers, variables, conditional branching, repetition, screen displays, etc. Assuming a configuration that uses a dedicated keyboard or character selection on the screen, check the entered lines in a list and then execute RUN. There is no fixed goal like in commercial games, and the focus is on learning how commands work while correcting grammatical errors.
