Robert,

I've meanwhile sat down and written up some how-to, primarily as a
reference for myself.  It is included below.  Note that even for a DLL
you're telling the OWL wizard to make an EXE project - hand-editing as
described below will take care of that diversion.

Cheers,                   Jochen


To transfer a project using OWL from BC++5.02 to BCB4:

0) Forget IDETOBPR.
1) Create a new project in BCB4 with the OWL wizard.
2) Make sure that no source file (.cpp) in the old project
   has the same name as the new project.
3) Add a line "#define WinMain" for an executable to the
   new main project source file, or "#define DllEntryPoint"
   for a DLL project, as shown below.
4) For DLLs, edit 4 lines in the .bpr file as shown below.
5) Add all files of the old project to the new one using the
   appropriate tool/button of BCB4.
6) Get a drink to relax.  You should be up and running.


Sample main file bc502.cpp for BCB4 project bc502.bpr
to accommodate a previous bc502 project of BC++5.02:

//--begin-file-bc502.cpp
#pragma hdrstop
#include <condefs.h>
USEUNIT("bc502main.cpp");   // Appears when adding file to project.
USEUNIT("bc502subs.cpp");   // Appears when adding file to project.
USERC("bc502res.rc");       // Appears when adding file to project.
//-----------------------------------------------------------------
#define WinMain
//--end-file-bc502.cpp



Sample main file bc502dll.cpp for BCB4 project bc502dll.bpr
to accommodate a previous bc502dll project of BC++5.02:

//--begin-file-bc502dll.cpp
#pragma hdrstop
#include <condefs.h>
USEUNIT("bc502dllold.cpp"); // Appears when adding file to project.
USEDEF("bc502dllold.def");  // Appears when adding file to project.
//-----------------------------------------------------------------
#define DllEntryPoint
//--end-file-bc502dll.cpp



Changes in a bc502dll.bpr file to convert from an .EXE to a .DLL:

Section:      # IDE SECTION
Entry:        PROJECT
.EXE has:     PROJECT=bc502dll.exe
.DLL needs:   PROJECT=bc502dll.dll

Section:      # IDE SECTION
Entry:        CFLAG1
Add flags:    -WD -tWD
Remove flags: -tW

Section:      # IDE SECTION
Entry:        LFLAGS
Add flags:    -Tpd
Remove flags: -Tpe

Section:      # IDE SECTION
Entry:        ALLOBJ
.EXE has:     ALLOBJ=c0w32.obj $(OBJFILES)
.DLL needs:   ALLOBJ=c0d32.obj $(OBJFILES)

End of changes
