3材料分析题3 / 10

　
Private Sub C1_Click()
Dim A$, B$, k%, n%
A$ = ""
？ = Asc("a") - Asc("A")
For k% = 1 To Len(Text1.Text)
B$ = Mid(？)
If B$ >= "a" And B$ <= "z" Then
B$ = String(1, Asc(B$) - n%)
Else
If B$ >= "A" And B$ <= "Z" Then
B$ = String(1, Asc(B$) + 32)
End If
End If
A$ = ？
Next k%
Text1.Text = A
End Sub
