Selecting Random values

[davk]

Hi there,

I am involving a program in which i have to select a value through a range of values, but i do not know precisely how to use random function in FORTRAN.

For example, I show you a small part of my data below. So, I need to divide each line into 4 part and pick just one "1" of each part.

211110122122
121011111110
121112111211
211121111111
100122221121
121101211211
121121111112
111200112111
112111110111
111211111112

In each part that i have three "1", I have to be able to select one of those randomly.

Help me please to solve this problem, coz i have been spending many days to solve that but i couldn't.

Thanks in advance
Davood
