When working with loops in Uniface, one of the most essential control flow statements you'll encounter is the break statement. Let me walk you through everything you need to know about this powerful tool! 🚀

📋 What is the Break Statement?

The break statement in Uniface 10.4 allows you to unconditionally exit a loop. It works with all major loop types:

• 🔁 for loops
• 🗂️ forentity loops
• 📝 forlist loops
• 🔄 repeat loops
• ⏳ while loops

🎯 How Does It Work?

In Repeat and While Loops

When you use break in repeat or while loops, the program flow immediately jumps to the statement that follows the nearest until or endwhile statement.

In For Loops

In for loops, break is typically used within an if block. The flow then passes to the command following the endfor statement.

⚠️ Important Note About Nested Loops

Here's something crucial to remember: when a break statement appears inside several nested loops, only the innermost loop is exited. This means if you have multiple levels of loops, break will only escape the immediate loop it's placed in, not all of them! 🎯

📊 Key Details

💡 Pro Tips

• ✅ Use break to exit loops early when a specific condition is met
• ✅ Perfect for search operations where you want to stop once you find what you're looking for
• ✅ Remember that it only affects the innermost loop in nested scenarios
• ✅ Always consider the flow control implications in your code design

🔚 Conclusion

The break statement is a fundamental tool for controlling loop execution in Uniface 10.4. Understanding how it behaves in different loop types and nested scenarios will help you write more efficient and readable code! 💪
