REXX Control Structures Tutorial | IF THEN ELSE, DO Loops, SELECT WHEN Explained.

Описание: Welcome to this in-depth REXX Control Structures Tutorial, where we break down the core logic-building tools used in REXX programming. Whether you're a beginner or brushing up your skills for mainframe scripting, this tutorial will help you master the essential control flow structures in REXX.

🔥 In this video, you'll learn how to use:
🔹 IF...THEN...ELSE – for conditional logic
🔹 DO Loops – including DO WHILE, DO UNTIL, DO FOREVER, DO n TIMES
🔹 SELECT...WHEN...OTHERWISE – for multi-condition branching
🔹 ITERATE & LEAVE – for better loop control

Each structure is explained with clear examples, real-world usage, and best practices for writing clean and maintainable REXX scripts.
