Origin Version (Select Help-->About Origin): 7.5SR5
Operating System: Win 2000SV
Is there any command to get an index number where the
specific data stored? The following is an example.
index,col_a
1,-2.7
2,-2.7
3,-11.6
4,8.8
5,6
If I want to get the index of max data, the following
scripts become too complicated! Especially when the data
length is very long and I have to devide the data using
"set -bs" and "set -es" commands.
sum(data_a);
loop(ii,1,wks.nrows)
{
if(data_a[ii]==sum.max)
{
index=ii;
first=ii;
break;
};
};
type $(index);

In your example you can use the limit command. Following gets the max value and its index in rows 101 to 200...
limit data_a -b 101 -e 200;
ymax=limit.ymax; // max Y value in range
imax=limit.imax; // index of that value
If you want the index for a specific value other than min or max use the list function...
i=list(123.456,data_a);
