数据表结构及记录分别如1图和2图所示，选择右键菜单中的“新记录”并输入相应数据，下列可能作为新记录的是（ ）
Dim c As String, s1 As String
s = Text1.Text
s1 = ""
For i = 1 To Len(s)
c = Mid(s, i, 1)
If c >= "A" And c <= "Z" Then c = Chr((Asc(c) - Asc("A")) Mod 10 + Asc("0"))
If c >= "4" And c <= "9" Then c = Chr(Asc(c) - Asc("4") + Asc("a") + 1)
s1 = c + s1
Next i
Text2.Text = s1

⑴将原文转换为若干行m列（m为奇数）的矩阵，最后一行若不足m个数据则以“#”填充。
⑵将矩阵中的数据，从末行末列数据开始以回路的方式提取字符。按顺序生成加密字符。例如对字符“helloworld”，m=3的加密过程如下图，其加密结果为“#lwleor#dolh”
