Here is a C++ module, step01.cpp, that immediately calls a C module, color1.c, (prints screen of text) and then returns to the C++ module (prints window).

I set the TARGET TYPE  = ‘Application’ 
and the PLATFORM = ‘WIN32.’ The program compiles and links fine, 
but when I run it, the *.C module is totally ignored, (like it is being “mangled” along with the CPP). 

If I set the TARGET TYPE  = ‘Application’ 
and the PLATFORM =        ‘DOS (standard),’ 
  . . then I get all kinds of problems from the CPP module.

----------------------- step01.cpp ------------------
#include <owl/pch.h>
#include <owl/applicat.h>
#include <owl/framewin.h>

extern "C" int color1(void);

class TDrawApp : public TApplication {
  public:
    TDrawApp() : TApplication() {}

    void InitMainWindow()
    {
      color1(); //<--- would this go here?
      SetMainWindow(new TFrameWindow(0, "Sample ObjectWindows Program"));
    }
};


int
OwlMain(int /*argc*/, char* /*argv*/ [])
{
return TDrawApp().Run();
}
------------------------------- color1.c -----------------
#include <stdio.h>
#include <conio.h>

char message[] = "C portion";

int color1(void )
{ //89
int col= 1;
int row=1;

textcolor(7);
textbackground(1);
clrscr();

while( col < 65 )  //print screenfull of text
{ //9
gotoxy( col, row );
printf(message); //

row++;
if( row == 23 )
{//28
col+=15;
row = 1;
}    //28

} //9

return (0);
} //89
