One would expect that by using the compiler option /DELETE_OBJ_ON_ERROR the object file of a program would be deleted in case of a compiler error. However, although the compiler reports 3 errors for the attached program(3 ERRORS [<DELETE_OBJ_ON_ERRORS> FTN95/Win32 v5.0.0]), the object file is created and the program is run.

I have run the program with FTN95 Version 5.0 and a bat file:

del comp.lis
del *.obj
del *.exe
ftn95 Delete_obj_on_errors.f95 /checkmate /underflow /DELETE_OBJ_ON_ERROR >> comp.lis
slink Delete_obj_on_errors.obj
sdbg Delete_obj_on_errors.exe


The program is:

WinApp
Program Delete_obj_on_errors
Implicit None
Real :: a

! Error: Time1, Time2 and i are not declared
! Although the program was compiled with
! /DELETE_OBJ_ON_ERROR the obj file is
! created and the program is run.

Call Cpu_Time ( Time1 )
a = 1.
Do i = 1, 2
a = a + 1.
End Do
Write (*,*) 'a = ', a
Call Cpu_Time ( Time2 )
write (*,*)'Processing time was',TIME2-TIME1, ' seconds'
End Program Delete_obj_on_errors

I suspect that the problem here is inadequate documentation.
/DELETE_OBJ_ON_ERROR is designed to delete object files of zero size.

This occurs when there are fatal compilation errors.

To make it work in other cases you must add /ERRFAIL.
