The Titan REXX-like Scripting Language (Titan RSL) is a computer programming language that draws inspiration from the robust, flexible syntax of IBM's Restructured Extended Executor (REXX). Developed by Titan Systems, it was designed to simplify and streamline scripting tasks for programmers. Its functionality extends beyond traditional scripting languages with its ability to handle complex data structures and object-oriented programming. The language has been lauded for its ease of use and versatility in various computing environments. Despite limited documentation available online, references to this software can be found in technical manuals published by Titan Systems.

First 20 minutes

General Titan REXX-like Scripting Language (Titan RSL) app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Titan REXX-like Scripting Language (Titan RSL) application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

What is your experience with Titan REXX-like Scripting Language (Titan RSL)?

I have been working with Titan RSL for over 5 years in various projects, developing, debugging, and optimizing scripts.

How would you debug a script in Titan RSL?

I would use the TRACE command in Titan RSL to debug a script. TRACE provides a detailed step-by-step execution of the script, which is useful in identifying errors or bugs.

Describe the difference between the INTERPRET and EVALUATE commands in Titan RSL.

INTERPRET command in Titan RSL executes a string as a command, while EVALUATE command evaluates an expression and returns the result.

What are the advantages of using Titan RSL?

Titan RSL is easy to learn, it offers powerful string handling capabilities, it has a rich set of built-in functions, and it supports both procedural and object-oriented programming.

How would you optimize a Titan RSL script for better performance?

I would optimize a Titan RSL script by reducing the number of I/O operations, using efficient data structures, and minimizing the use of expensive operations like string concatenation.

Next 20 minutes

Specific Titan REXX-like Scripting Language (Titan RSL) 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.

What is the significance of the SAY command in Titan RSL?

The SAY command in Titan RSL is used to print a line of text to the console. It's equivalent to the print statement in other programming languages.

How would you handle errors in Titan RSL?

I would handle errors in Titan RSL using the SIGNAL command to catch exceptions and the CONDITION() function to retrieve information about the error.

What are the data types supported by Titan RSL?

Titan RSL supports two basic data types: strings and numbers. However, it can also handle complex data structures like arrays and objects.

Describe the difference between the PARSE and ARG commands in Titan RSL.

PARSE command in Titan RSL is used to split a string into tokens, while ARG command is used to retrieve the arguments passed to a routine.

How would you implement recursion in Titan RSL?

I would implement recursion in Titan RSL by writing a function that calls itself. The function should also have a condition to break the recursion to avoid infinite loops.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Titan REXX-like Scripting Language (Titan RSL).

What does this simple Titan RSL code do?
x = 5;
y = 10;
print(x+y);
This code declares two variables x and y, assigns them the values 5 and 10 respectively, and then prints the sum of x and y, which is 15.
What will be the output of this Titan RSL code?
string = 'Hello, Titan RSL';
print(string[7:11]);
This code will output the substring 'Titan' from the original string 'Hello, Titan RSL'. The indices 7 to 11 correspond to the word 'Titan'.
What will this Titan RSL code do with the array?
array = [1, 2, 3, 4, 5];
array.push(6);
print(array);
This code declares an array with elements 1 to 5, then adds the number 6 to the end of the array using the push method. The print command will output the updated array [1, 2, 3, 4, 5, 6].
What does this Titan RSL code do in terms of threading?
thread t1 = new thread(function() { print('Hello, Titan RSL'); });
t1.start();
This code creates a new thread t1 and assigns a function to it that prints 'Hello, Titan RSL'. The start method then initiates the execution of this thread.

Wrap-up questions

Final candidate for Titan REXX-like Scripting Language (Titan RSL) 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 Titan REXX-like Scripting Language (Titan RSL) application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the string manipulation commands in Titan RSL?

Titan RSL provides several commands for string manipulation, including SUBSTR for extracting a substring, POS for finding the position of a substring, and STRIP for removing leading and trailing spaces.

How would you handle file I/O operations in Titan RSL?

I would handle file I/O operations in Titan RSL using the LINEIN, LINEOUT, CHARIN, and CHAROUT commands for reading and writing data.

Describe the difference between the PULL and PUSH commands in Titan RSL.

PUSH command in Titan RSL places a line of text onto the stack, while PULL command retrieves a line of text from the stack.
