System_ tweak for window :

How to modify:
goto to your mod folder and open pub.mod then look from stdc.mod, in stdc.mod you will find a file called stdc.c load it up and modify the following code.

From:

int system_( const char *args ){

	int res,nhandles;		
	HANDLE handles[2];
	STARTUPINFO si={sizeof(si)};
	PROCESS_INFORMATION pi={0};	
	
	if( !CreateProcess( 0,(char*)args,0,0,1,0,0,0,&si,&pi ) ) return -1;
	
	WaitForSingleObject( pi.hProcess,INFINITE );

	res=GetExitCodeProcess( pi.hProcess,(DWORD*)&res ) ? res : -1;
	
	CloseHandle( pi.hProcess );
	CloseHandle( pi.hThread );

	return res;
}

To:

int system_( char args[] ){

	int res,nhandles;
	int letter='?';
	int timeout = INFINITE;
	HANDLE handles[2];
	STARTUPINFO si={sizeof(si)};
	PROCESS_INFORMATION pi={0};
	
        if( strchr( args, letter ) ) 
	{
		args[ strlen(args)-2 ] = 0;
		timeout=0;
	}
	
	if( !CreateProcess( 0,(char*)args,0,0,1,0,0,0,&si,&pi ) ) return -1;
	
	WaitForSingleObject( pi.hProcess,timeout );

	res=GetExitCodeProcess( pi.hProcess,(DWORD*)&res ) ? res : -1;
	
	CloseHandle( pi.hProcess );
	CloseHandle( pi.hThread );

	return res;
}

Then click Build Modules in the menu bar and your off.

Example:
By adding the " ?" at the end of the path this allows the program to continue instead of waiting for the window to end.

Graphics 800,600,0

system_ "notepad.exe ?"

While not keyhit( key_escape )

flip
wend
end

you can still use this command the default way and it will work as usual.

system_ "notepad.exe"

Thanks,

Under windows 2000/XP/NT the following will work as well, without modifying any modules:

system_ ("cmd /c start calc.exe")

But that won't work on Win95/98, and not on Linux & Mac either. (Is the module change as outlined above cross-platform, or windows-only?)
