(Not that I really want to get involved in this silly topic, but...)

Why does C "need" the equiv of iter/leave?   You can do the same things
in C that you can do in RPG...   I dont understand your statement...

This construct in C does exactly the same thing as a SELECT in RPG:

if (condition1) {
}
else if (condition1) {
}
else if (condition3) {
}
else {
}

(RPG Equiv:)

SELECT
WHEN (condition1)
WHEN (condition2)
WHEN (condition3)
OTHER
ENDSL


And if conditions are all comparisons of the same variable, you can use
switch as well, like:

switch (variable) {
    case 1:
    case 2:
    case 3:
    default:
}


Why does either method lend itself more to ITER/LEAVE (or continue/break)
than the other?!
