AMOS Professional BASIC+ is a high-level programming language developed by François Lionet and Constantin Sotiropoulos in the late 1980s. It was originally designed for the Commodore Amiga, a popular personal computer at that time. The software was released by Europress Software and quickly gained popularity due to its simplicity and ease of use, making it accessible to beginners in programming. AMOS Professional BASIC+ incorporated advanced features such as sprite handling and collision detection, which were particularly useful for game development. Despite its discontinuation after the decline of Amiga computers, it remains an important part of computing history.

First 20 minutes

General AMOS Professional BASIC+ app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in AMOS Professional BASIC+ application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you describe the primary use of AMOS Professional BASIC+?

AMOS Professional BASIC+ is primarily used for game development, particularly for the Amiga computer system. It's a high-level programming language that simplifies the process of creating games by providing built-in commands for common game programming tasks.

What are some of the key features of AMOS Professional BASIC+?

Some key features of AMOS Professional BASIC+ include its easy-to-understand syntax, built-in commands for graphics and sound, and its ability to compile programs into standalone executables.

Describe the difference between AMOS Professional BASIC+ and other versions of BASIC.

AMOS Professional BASIC+ is specifically designed for game development on the Amiga computer system. It includes built-in commands for handling graphics, sound, and user input, which are not typically found in other versions of BASIC.

How would you handle error handling in AMOS Professional BASIC+?

AMOS Professional BASIC+ includes a built-in error handling system. You can use the ON ERROR command to specify a subroutine that should be executed when an error occurs. This subroutine can then handle the error in an appropriate way, such as by displaying an error message to the user.

What are the steps to compile a program in AMOS Professional BASIC+?

To compile a program in AMOS Professional BASIC+, you would first write your program in the AMOS editor. Then, you would select the 'Compile' option from the 'Program' menu. This will create a standalone executable file that can be run independently of the AMOS environment.

Next 20 minutes

Specific AMOS Professional BASIC+ development questions

The next 20 minutes of the interview should focus on the candidate's expertise with specific backend frameworks, their understanding of RESTful APIs, and their experience in handling data storage and retrieval efficiently.

How would you implement a game loop in AMOS Professional BASIC+?

A game loop in AMOS Professional BASIC+ can be implemented using a DO...LOOP structure. Inside the loop, you would include code to handle game logic, user input, and screen updates. The loop would continue until a certain condition is met, such as the player losing all their lives or quitting the game.

What are the key considerations when optimizing code in AMOS Professional BASIC+?

When optimizing code in AMOS Professional BASIC+, it's important to consider factors such as the efficiency of your algorithms, the use of built-in commands, and the management of memory. You should also aim to write clear and readable code, as this can make it easier to identify and fix performance bottlenecks.

Describe the difference between global and local variables in AMOS Professional BASIC+.

In AMOS Professional BASIC+, global variables are accessible from anywhere in the program, while local variables are only accessible within the subroutine in which they are declared. Using local variables can help to prevent naming conflicts and make your code easier to understand.

How would you implement collision detection in AMOS Professional BASIC+?

AMOS Professional BASIC+ includes built-in commands for sprite collision detection. You can use the SPRITE HIT command to check if two sprites have collided, and then handle the collision in an appropriate way, such as by reducing the player's health or ending the game.

What are the steps to create a sprite in AMOS Professional BASIC+?

To create a sprite in AMOS Professional BASIC+, you would first create the sprite image using the AMOS sprite editor. Then, you would use the LOAD SPRITE command to load the sprite into memory, and the SPRITE command to display the sprite on the screen.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with AMOS Professional BASIC+.

What does this simple AMOS Professional BASIC+ code do?
Print 'Hello, World!'
This code prints the string 'Hello, World!' to the console.
What will be the output of this AMOS Professional BASIC+ code?
For i = 1 To 5 : Print i : Next i
This code will print the numbers 1 through 5, each on a new line.
What does this AMOS Professional BASIC+ code do?
Dim a(5) : For i = 1 To 5 : a(i) = i * 2 : Next i : For i = 1 To 5 : Print a(i) : Next i
This code creates an array of 5 elements, assigns each element a value that is twice its index, and then prints each element's value.
What does this AMOS Professional BASIC+ code do?
Procedure P() : For i = 1 To 5 : Print i : Next i : End Proc : Run P
This code defines a procedure named P that prints the numbers 1 through 5, and then calls the procedure.

Wrap-up questions

Final candidate for AMOS Professional BASIC+ Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle AMOS Professional BASIC+ application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

How would you handle user input in AMOS Professional BASIC+?

AMOS Professional BASIC+ includes built-in commands for handling user input. You can use the INKEY$ command to check if a specific key has been pressed, and the MOUSE command to get the current position of the mouse. These commands can be used in a game loop to continuously check for user input.

Describe the difference between procedural and object-oriented programming in the context of AMOS Professional BASIC+.

AMOS Professional BASIC+ is primarily a procedural programming language, which means that programs are structured around procedures or subroutines. However, it also includes some features of object-oriented programming, such as the ability to create custom data types with associated procedures. This allows for a more modular and organized approach to programming.

How would you implement a scoring system in AMOS Professional BASIC+?

A scoring system in AMOS Professional BASIC+ could be implemented by creating a variable to store the player's score, and then updating this variable whenever the player performs a scoring action, such as collecting a power-up or defeating an enemy. The score could then be displayed on the screen using the PRINT command.
