The remainder of the mdl.bat file compiles and links the model equations to create sim.dll.
CL /c /DWIN32 mdl.c
This line compiles mdl.c. If there is an error, or if mdl.obj was not created then the batch file will issue an error message.
LINK /DLL /OUT:%3.dll /def:%1sim.def mdl.obj
This line links the object file to create the dll. If there is an error it is reported.
These commands will work for Micsosoft C compilers. If you are using a different compiler you will need to adjust your command lines appropriately.
