[ncl-talk] daily average

[Dennis Shea]

Guido's comment about a space between 'end' and 'do ' is correct.
Further, you can not change the do loop index values within the do loop.
There are other errors.

It is best to use print statements to follow the execution of your code.

A code segment that should worl is:

  Tpj=new((/31,37,73,144/),float)
  tStrt = 0
  tLast = 3
  do j=0,30
     print("jday="+(j+1))
     Tpj(j,:,:,:)=dim_avg_n(T(tStrt:tLast,:,:,:),0)
     tStrt = tStrt+4
     tLast = tLast+4
  end do
