I've got several columns of data; each columns refers to one element. Far
each elements the arrays are experimental values I call them "steps"(about
100 arrays for each element)

For every element ,i want to automatically check when values in array exceed
1


Example: for two elements

step E1 E2
1 0,23 0,8
2 0,56 0,87
3 1,02 0,90
4 1,89 0,91
5 3 0,98
...

70 30 1,2
...
100 54,1 56,5


I want to know, for each element (=column) the FIRST step at which value1 ,
or better, the step "i" between steps "i-1" and "i+1" where i-1<1 and i+11

The result would be sthg as
Step
E1 3
E2 69
E3 12
E4 36
... ...

TIA for evey help
