oklopp us a variable of the enum type loop, so you can assign either NO

An enum is a type, which in this case can have one of two values, YES
and NO.

Assigning any other value to a loop is undefined. Unfortunately C
compilers don't regard this as an error, which renders enums little more
than symbolic constants.

gcc gives a warning when you do a switch on an enum type, indicating
that you have failed to explicitely specify behavior for any of the
listed cases. I find that very useful.
