Simple iIf Example

iIf( server.OS.NAME == "Bacon", de( "Running Bacon OS" ), de( "Not Running Bacon OS" ) );

Simple Example using Ternary Operator Instead

Instead of using iif, you should use the ternary operator

((server.OS.NAME == "Bacon") ? "Running Bacon OS" : "Not Running Bacon OS");

Result: Not Running Bacon OS
