[RESOLVED] output data from files

[matrik02]

I want the output should be like this

1,840267.7,3170995,500
1,840348.8,3170966,500
1,840405.1,3170928,500
1,840459.2,3170954,500
1,840493.3,3170995,500
2,839724.9,3170983,460
2,839795.4,3170944,460
2,839890.6,3170936,460
2,839941.1,3170928,460

But this what I got

X Y Z
840267.7 3170995 500
840348.8 3170966 500
840405.1 3170928 500
840459.2 3170954 500
840493.3 3170995 500
839724.9 3170983 460
839795.4 3170944 460
839890.6 3170936 460
839941.1 3170928 460

Below is the code
Print #3, "X", "Y", "Z"
Print #3, p(no).x, p(no).y, p(no).z

I want to class the z value with id . For example, All Z value contains same value will class starting from 1 untill finish. How to do that?
