Panorama 4GL is a high-level programming language developed by ProVUE Development, a software company founded in 1978. This language is specifically designed for database management, offering robust features for data manipulation and analysis. It gained popularity in the 1980s and 1990s, particularly among Apple Macintosh users. Panorama 4GL supports both procedural and object-oriented programming paradigms, providing flexibility for developers. Its legacy continues with Panorama X, a modern version that incorporates contemporary programming features while maintaining the original language's core principles.

First 20 minutes

General Panorama 4GL app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Panorama 4GL application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you define Panorama 4GL?

Panorama 4GL is a high-level programming language used for database management and reporting. It allows developers to create complex database applications with less coding compared to other languages.

What are the key features of Panorama 4GL?

Key features include high-level abstraction, strong data typing, procedural and declarative programming, and built-in functions for database management.

Describe the difference between Panorama 4GL and SQL.

While both are used for database management, Panorama 4GL is a high-level language that provides more abstraction and built-in functions, making it easier to create complex applications. SQL, on the other hand, is a query language primarily used for managing and manipulating databases.

How would you handle errors in Panorama 4GL?

Panorama 4GL provides several error handling mechanisms, including exception handling and error codes. The choice of mechanism depends on the specific requirements of the application.

What are the data types supported by Panorama 4GL?

Panorama 4GL supports several data types, including integer, decimal, string, date, and boolean.

Next 20 minutes

Specific Panorama 4GL 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.

Describe the difference between a procedure and a function in Panorama 4GL.

A procedure is a set of instructions that performs a specific task, while a function is a set of instructions that returns a value. In Panorama 4GL, both can be used to encapsulate and reuse code.

How would you optimize a Panorama 4GL application?

Optimization strategies include minimizing database access, using appropriate data types, and optimizing code structure. Profiling tools can also be used to identify performance bottlenecks.

What are the advantages of using Panorama 4GL over other programming languages?

Advantages include high-level abstraction, strong data typing, and built-in functions for database management, which can result in less coding and faster development time.

Describe the difference between strong and weak typing in Panorama 4GL.

Strong typing means that the type of a variable is checked at compile time, which can prevent type-related errors. Weak typing, on the other hand, allows more flexibility but can lead to runtime errors.

How would you test a Panorama 4GL application?

Testing strategies include unit testing, integration testing, and system testing. Automated testing tools can also be used to improve testing efficiency.

Oops! Something went wrong while submitting the form.

At this point, a skilled Panorama 4GL engineer should demonstrate strong problem-solving abilities, proficiency in Panorama 4GL programming language, and knowledge of software development methodologies. Red flags include lack of hands-on experience, inability to articulate complex concepts, or unfamiliarity with standard coding practices.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Panorama 4GL.

What does this simple Panorama 4GL code snippet do?
DISPLAY 'Hello, World!';
This code displays the string 'Hello, World!' on the console.
What does this Panorama 4GL code snippet do?
DEFINE VARIABLE i AS INTEGER NO-UNDO.
FOR i = 1 TO 10 DO
DISPLAY i.
END.
This code defines a variable 'i', then uses a FOR loop to iterate from 1 to 10, displaying the value of 'i' with each iteration.
What does this Panorama 4GL code snippet do?
DEFINE VARIABLE arr AS INTEGER EXTENT 5 NO-UNDO.
DO i = 1 TO EXTENT(arr):
ASSIGN arr[i] = i * 10.
END.
This code defines an array 'arr' with 5 elements. It then assigns the multiples of 10 to each element in the array.
What does this Panorama 4GL code snippet do?
DO TRANSACTION:
CREATE customer.
ASSIGN customer.name = 'John Doe'.
END.
This code creates a new 'customer' record within a transaction block and assigns the name 'John Doe' to the 'name' field of the 'customer' record.

Wrap-up questions

Final candidate for Panorama 4GL 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 Panorama 4GL application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the limitations of Panorama 4GL?

Limitations include lack of support for object-oriented programming, limited control over low-level details, and less flexibility compared to lower-level languages.

Describe the difference between procedural and declarative programming in Panorama 4GL.

Procedural programming involves writing instructions that tell the computer what to do step by step, while declarative programming involves writing expressions that describe what the result should be, without specifying how to achieve it.

How would you debug a Panorama 4GL application?

Debugging strategies include using the built-in debugger, adding debug statements to the code, and using logging to track the execution of the application.
