You will need to have d3lib.dll which is dependant on the following fortran runtime library files:-
-
LIBIFCOREMD.DLL
-
LIBMMD.DLL
These are therefore included in %PDMSEXE% and with this DARs release.
-
-
If MSVCP71.DLL and MSVCR71.DLL are not already installed, obtain them from Microsoft.
If, when you start up your DARs application, you get a Windows popup such as the following, this indicats that the dynamic link library d3lib.dll could not be found in the specified path.

-
Ensure that that PATH is set to include the location of d3lib.dll, which is normally %PDMSEXE%\dars.
-
If an application program enters D3INIT successfully, program debugging can be assisted by use of the FULL monitoring level. You can switch this on in D3INIT, or by a later call to D3UMON.
