有如下VB程序段:
Dim i As Integer,c As String,s As String,t As Integer
Dim s2 As String,pwd As String
s=Text1.Text:pwd="71zhYEAR":s2="":t=0
For i = 1 To Len(s)
c=Mid(s,i,1)
If c>="0" And c<="9"Then
t=t*10+Val(c)
Else
s2=s2+Mid(pwd,t Mod 8+1,1)
End If
Next i
Text2.Text=s2
运行该程序段,在文本框Text1中输入“20B13A8”,文本框Text2输出的是( )
