RE: Problem with "Range Check Error"

[Michaël Kummert <kummert@xxxxxxxxxxxxx>]

Dear Apple Chan,

A range check error is generated when an array goes out of bounds.
Unfortunately, as mentioned in previous replies, it is not always easy to
find out which array causes the problem.

Here are some frequent causes of range check errors:

- Equation with missing right side
  Example:
  EQUATIONS 3
  VAR1 = 10
  VAR2 =
  VAR3 = 20
  
- Attempt to use an output number in an equation without using the brackets
  EQUATIONS 2
  VAR1 = [1,1]*10.0  ! OK
  VAR2 = 10.0+1,1    ! INCORRECT

Other typical mistakes leading to range check errors are related to maximum
number of nodes (e.g. if a component allows up to 10 nodes and you try using
11 nodes, sometimes the component does not catch the error and you get a
range check error)

If you have a Fortran debugger, you can use it to track the problem. If you
are using Compaq Visual Fortran, make sure to set your debugger to stop when
this kind of error occurs.
To do so: 
- Open the TRNSYS project in CVF. 
- Press F11 (Step into) to start debugging 
  the program and stop at the first instruction. 
- Go to Debug/Exceptions
- Select all exceptions, check "Stop always" and 
  click OK
- Press SHIFT+F5 to abort the program
- Press F5 again to enter the program in Debug 
  mode without stopping at the first instruction

Finally, please let us know if you find the problem, we will try to fix that
in a future release.
