This shows that the error occurs inside your DLL. Error 68 is described 
in the Visual Compaq Fortran help (I pasted the text here below).

severe (68): Variable format expression value error
FOR$IOS_VFEVALERR2. The value of a variable format expression was not 
within the range acceptable for its intended use; for example, a field 
width was less than or equal to zero. A value of 1 was assumed, except 
for a P edit descriptor, for which a value of zero was assumed.

I suggest that you step through your code looking for the WRITE 
instruction that causes the problem. You can debug your DLL by making it 
the "active" project in CVF.

The fact that the error ocurs writing to CONOUT suggests that you have a 
"WRITE(*,...)" or WRITE(LUN,...) where LUN=1 (and I don't think you will 
see the output anywhere by the way because this is supposed to write to 
the screen). Some "write" problems also occur when sharing logical units 
between DLL's if the project is not linked against the DLL version of 
standard libraries.

Kind regards,
