Another problem with the readln() function

I assume that the issue is the same as in the previous discussion: by (un)commenting 'readln' statements, the contents of the datafile no longer matches what the model is trying to read, and you are not reading information into the intended structures.

You might consider switching to work with Mosel's text data format (data files accessed through 'initializations from' blocks) then data entries are identified by labels, which would resolve the problem with skipping entries. - Notice however, that this would require some editing of the data file.
