I am trying to figure out how to represent missing values in an array with a value I know won't be in there for example -99.9. A sample of my code, is below. The array "pro" has been read in from a data file of numeric values. I need the do loop range to stay fixed because other parts of the array that I will be working with fill the range, but this specific part does not. Code (Text): DO i=1,31 PRINT *, pro(1,3,i) END DO I have tried setting the array equal to -99.9 before the loop but all that prints is "*****".
