The missing values are filled importantly from the next good value in a column.

Following that criteria, your output for the sample input should be:

0.01,2,1
0.02,2,3
0.03,2,3
0.04,2,4
0.05,5,4
0.06,5,4

Which is quite different from the sample output you've provided?

Ie: 

      next        next
      good        good 
      valu        valu 
0.01,  v  -999.9,  *        1   
0.02,  v  -999.9,  v   -999.9   
0.03,  v  -999.9,  *        3
0.04,  *       2,  v   -999.9
0.05,  v  -999.9,  v   -999.9
0.06,  *       5,  *        4
