Get 1 string and split into two.

fi866yiec826ze/W1-1

I want it to become

W1-1

fi866yiec826ze

how would I do this?

tokenat(fi866yiec826ze/W1-1,0,"/") = fi866yiec826ze

tokenat(fi866yiec826ze/W1-1,1,"/") = W1-1

Thanks you so much. I was gonna write it using a bunch of stuff but you made a simpler way.
