because Explode power Yes in the entrapment the Leerstrings too nothing other, as the first element something zuzuweisen; namely a Leerstring.
viewing one against a Leerstring as present, so entrapments all these difficulty lane. One No seiendes element is then weder Leerstring yet zero, separate crept No, with which The Size the Arrays eindeutig bestimmbar is.
Womit a problem to have You seem, is, that Explode at all The work aufnimmt. All the philosophische stuff could one itself save, if one it crept so made:
CompileMarkSeparation
case Text$<> : matrix$[] = Explode(Text$,)

Explode power namely what it should: it divides whom sustained Text whom Delimitern ensprechend on. the first, what it finds, is a Leerstring, the of course nothing contains, therefore but yet long not nothing is. this Leerstring becomes then the first element the Arrays allocated, thereafter there No further Teilstring More - you're no Leerstrings, separate objectively not existent - , with which Explode its work Done has.
One example for is that here:
CompileMarkSeparation
cls
var matrix$[] = Eplode(;;;;,;)
print SizeOf(matrix$[])
waitinput
end

loudly of my Logik comes five out, what sustain You?
CompileMarkSeparation
cls
var matrix$[] = Eplode(;,;)
print SizeOf(matrix$[])
waitinput
end

loudly of my Logik comes two out, comment two out, what Dou you mean? one? 

PS: forgive me The Langatmigkeit, I have The next two weeks none Unterricht More.
