Short hand IF-Else statements Merged

Coding is all about if statements and most of the times we code a simple "If this then that, else this " logic. 

It would be nice with a short hand format to this to ease the coding experience somewhat. The goal would be to have a quick, short (one line) way of assigning a value to a variable with a logical condition. I know there are different ways to solve this today with IF statements or SELECT statements. And they are great, especially when you have many different cases/options/conditions.  But a lot of times there is just an assignment with a simple "if this then that, else this" logic. 

Would clean up code a little and also mimic what can be done in other languages.

How to do this today: 
If NbrOfRows > 1;
  multiRowProcessing = 'Y';
else;
  multiRowProcessing = 'N';
endif;

How it could be solved with a new %BIF  as an example.    Possible BIF names: %IF,  %IFELSE  or something similar
multiRowProcessing  = %IFELSE (NbrOfRows > 1  : 'Y' : 'N' );     //    %BIF (Expression to evaluate : value if true : value if false )

How it could be solved with existing or similar opcode logic (Similar to SQL case)
multiRowProcessing   = CASE (NbrOfRows > 1 ) THEN  'Y' ELSE 'N'  END ;

    Your request is a duplicate of IBM Idea IBMI-I-1417 ("RPG - Conditional (Ternary) Operator (?:) in EVAL operation"). https://ibm-power-systems.ideas.ibm.com/ideas/IBMI-I-1417

    Please use that Idea to cast a vote or add a comment.

    One of the comments for that Idea has a response from IBM that suggests that new built-in function %IF would be added to fulfill that requirement. The comment says "If IBM provides this feature, it would most likely be in the form of a %IF built-in function rather than using the ? : syntax. %IF(condition : true value : false value)"
