How can we create a .com file using C / C ++? Is it possible?
Edit: I was able to successfully create a com file using darin suggestions. But somehow the exe file of the next program cannot be converted to a com file. I get the message "File cannot be converted" exe2bin. I am using Borland Turbo C ++ 3.0. Any suggestions?
#include <dos.h>
void interrupt (*oldint65)( );
char st[80] = {"Hello World$"};
void interrupt newint65(void);
void main()
{
oldint65 = getvect(0x65);
setvect(0x65, newint65);
geninterrupt (0x65);
geninterrupt (0x65);
geninterrupt (0x65);
setvect(0x65, oldint65);
}
void interrupt newint65( )
{
_AH = 0x09;
_DX=(unsigned int)st;
geninterrupt (0x21);
}
