// 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).

? Empty( cString ) // --> TRUE

IF ! Empty( cString ) // --> FALSE
