dim OneChar as string
for i = 0 to MyTextVar.Length-1
OneChar = MyTextVar.SubString2(i, i + 1)
next

You could replace
OneChar = MyTextVar.SubString2(i, i + 1)
by
OneChar = MyTextVar.CharAt(i)

Grazie Luca! in effetti già avevo adottato questa soluzione ma non mi funzionava quando la stringa a lunghezza 1.....gestendo la cosa ora funge tutto
