What is wrong? You mis-understand usage of last three parameters
in DialogAddRequest. Corrected source is given below (some
unelegant details are also changed, like unnecessary usage of
some global variables, etc.), but anyway you will learn how
to use request boxes correctly. Examine parameters for
DialogAddRequest carefully!

Using a callback function, you can overwrite the status line
with whatever you want. Look about DialogNew in tigcclib doc
for description what is callback function (said simply, this is
an user function which is called internally from the dialog
applet; for example callback is called whenever an item in the
dialog gets a focus).

I hope that I helped. The source follows:

#define SAVE_SCREEN

#include <nostub.h>
#include <all.h>

int _ti89,_ti92plus;

static char Email[100][30]={{}};
static char Address[100][30]={{}};
static char CSZ[100][30]={{}};

int MyCallBack(int a,long b)
{
  ST_helpMsg("Whatever you want...");
}

int editen(int en)
{
  char buffer[140];

  else

    }

void ab(void)

void cal(void)
{

int _main()

  int result=1;
