[ncl-talk] Subscript out of range error

[Dennis Shea]

The NCL Examples are meant as a guide toward usage ..... not plugin a
dataset
and it will work.

The whole point of my previous response

     ii = ind(apr.ge.levels(i).and.apr.lt.levels(i+1))
     print("i="+i+"   ii="+ii)    ; basic debug approach
     data2d(i,ii) = apr(ii)

was to examine the printed output. You did not include any of the
information. Only

 "warning:Argument 0 of the current function or procedure was coerced to
the appropriate type
and thus will not change if the function or procedure modifies its value
fatal:Dimension size mismatch on subscript #1, left-hand and right-hand
side dimensions do not match"

===
subscript 1 is 'ii' in data2d.

Here is even more info for you to print and look at:

    do i=0,nlevels-2

        print("i="+i+"   levels(i)="+levels(i)+"
levels(i+1)="+levels(i+1) )

        ii = ind(apr.ge.levels(i).and.apr.lt.levels(i+1))
        if (.any(ismissing(ii))) then
            print("ii has missing values: ii="+ii)
        else

            nii = dimsizes(ii)
            print("i="+i+"   nii="+nii)

            data2d(i,ii) = apr(ii)
            labels(i) = levels(i) + ":" + levels(i+1)

            delete(ii)
       end if
    end do
