Find the minimum value

Hi there

I have generated a column containing 100.000 values. Sample:
Code:
94.971
101.468
73.120
100.601
102.329

I need to find the minimum value in this file and I must know which row it is in (no sorting).

I hope you can help!

Thanks!

The poster need know: "1. minimum value and 2. which row it is in "

Your code has same problem as radoulov's, that's why I update radoulov's code, and paste here.
