// in Harbour we have several functions to check emptiness of a string, f.e. hb_IsNull(), Len(), Empty() et.c., |
|||
// we can also use comparison expressions like [cString == ""] and [cString != ""], yet the most convenient |
|||
// of them is `Empty()` (but that depends on personal coding style). |
