I would write:

	Maske.Index = CInt(wert[0]) - 1


but it is said that "gambas has automatic type conversion": I can't 
understand it fully, because it seems to me that your example should 
work, and also could (should?) work the following:

	Maske.Index = wert[0] - 1


To let this last line work, gambas should understand that the whole 
expression to the right of the "=" should be an integer, and convert the 
wert[0] string to an integer; and this is the same case as your first 
temptative.
