In RPG (Report Program Generator) programming, various program control structures and conditional logic constructs are used to control the flow of execution and make decisions based on certain conditions. These structures and constructs help in creating flexible and efficient RPG programs. Let's outline some of the key program control structures and conditional logic used in RPG programming:
1. Sequential Control:
Sequential control structures allow the program to execute instructions in a sequential order, one after the other. RPG programs follow a top-down approach where instructions are executed line by line unless specified otherwise. The program control flows from one statement to the next until it reaches the end or encounters a branching or looping construct.
2. Branching:
RPG provides branching constructs that allow altering the flow of control based on specific conditions. The commonly used branching constructs include:
* IF-ELSE-ENDIF: The IF-ELSE-ENDIF construct is used to evaluat....
