[TRNSYS-users] Confusion in Type42

[David Bradley]

Wimolsiri,
   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.
Kind regards,
  David
