Problems with StrAToI

[Arne Gemsa]

Hi,

I´ve got a problem with StrAToI. I´ve got the following code for Palm OS 5.4 on 
a T5:

UInt32 TextUtilsExtractVersion(const Char *pSourceStr, const UInt32 *pPos)
{
  UInt32 i = *pPos;
  UInt16 len = StrLen(pSourceStr);
  Boolean leave = false;
  UInt32 ret = 0;
  char digit;
        
  //search for first numeric character
  while ( !leave && i < len)
  {
    digit = *(pSourceStr+i);
  
    if (TxtCharIsDigit(digit))
    {
      FrmCustomAlert(CUSTOMALERT, "Number found", &digit, " "); 
      ret += StrAToI(&digit);
    }else
    {
      if (ret!=0) leave = true;          
    }
                 
    i++;
  }
        
  return ret;
}

TxtCharIsDigit(digit) found a numeric character but StrAToI returns 0. Why?

Regards
Arne
