It can be something like this:
Sub Geographer
Dim oDoc As Variant
Dim oSearchDescriptor As Variant
Dim oDictionary As Variant
Dim oReplace As Variant
Dim oStatusIndicator As Variant
Dim i As Long, j As Long
oDoc = ThisComponent
oStatusIndicator = oDoc.getCurrentController().getStatusIndicator()
oDictionary = Array( _
Array("America", "USA", "Mexico", "Canada", "Honduras"), _
Array("Asia", "China", "India", "Vietnam"), _
Array("Europe", "Ukraine", "Italy", "France", "Germany"), _
Array("Africa", "Qatar", "Tunisia") )
oSearchDescriptor = oDoc.createSearchDescriptor()
oStatusIndicator.start("", UBound(oDictionary)+1)
For i = LBound(oDictionary) To UBound(oDictionary)
oReplace = oDictionary(i)
oSearchDescriptor.setReplaceString(oReplace(0))
oStatusIndicator.setText(oDictionary(i)(0))
oStatusIndicator.setValue(i+1)
For j = 1 To UBound(oReplace)
oSearchDescriptor.setSearchString(oReplace(j))
oDoc.replaceAll(oSearchDescriptor)
Next j
Next i
oStatusIndicator.end()
End Sub
