Hello Jim,
having delved into the world of Dlls, this is the only way I know of exporting functions to the outside world using the Declare statement, this example pops up a ChooseColor() dialog box, to compile this into a dll from Visual Studio using C++, use File/New Project Win32dll Application

#include "windows.h"
#include "commdlg.h"

#define DllExport extern "C" __declspec (dllexport) 

DllExport int PKColor(int iInitColor) ;


static COLORREF crCustColors[256] ;
static CHOOSECOLOR cc ;

int WINAPI DllMain(HINSTANCE hinstance,DWORD fdwreason,PVOID pvReserved)
{
	return TRUE;
}



DllExport int PKColor(int iInitColor)

{
	cc.rgbResult      = iInitColor ;
	cc.lStructSize    = sizeof (CHOOSECOLOR) ;
	cc.hwndOwner      = NULL ;
	cc.hInstance      = NULL ;
	cc.lpCustColors   = crCustColors ;
	cc.Flags          = CC_FULLOPEN | CC_RGBINIT ;
	cc.lCustData      = 0 ;
	cc.lpfnHook       = NULL ;
	cc.lpTemplateName = NULL ;
	ChooseColor (&cc) ;
	return cc.rgbResult ;
}
	



having compiled it, use this code from the VFP command window



Declare integer PKColor in my.dll integer nColor

nColor = 0
nColor = PKColor(nColor)

by passing nColor on successive calls, you highlight your previously selected colour
