(EL-5030) Prime Factors

[Didier Lachieze]

Nice program! I've entered it on my EL-5030 but it returns 0 for any input.
I double checked the program in my EL-5030 vs. your listing and I don't see any difference.
However I'm wondering if the following sequence is correct:

Code:

            =N=>[
                C,
                X/C=>X
                <-\
            ]

What is the meaning of C, ?
