The structure of external data files read by the DATA, DYNDATA, or
DynamicData subroutines is that the first line in the file contains the
value of the highest order independent variable. Thus if you have three
independent variables, line 1 in the data file should contain the values
of the "third" independent variable. Line 2 should contain the
values of the "second" independent variable and line 3 should
contain the values of the "first" independent variable. This
structure makes it easier to add new independent variables (and the
dependent variables that go along with them) to data files; the new
independent variables go at the top of the file and the new corresponding
dependent variables go in a block at the beginning of the data section
instead of scattered throughout the data section.<br>
Kind regards,<br>
