七、附录：源程序列表
由于源代码繁多，限于篇幅，无法一一列举，现只公布部分代码，具体以系统实物为准。下面是录入试题.asp文件：
＜script language="VBScript"＞
＜!-- 'Written by HeKai 2001
Function datacheck()'确保前台输入数据合法
dim errflag, msg
errflag = True
if Len(Trim(luru.xzsj.value)) = 0 Then

ElseIf Len(Trim(luru.stnr.value)) = 0 Then
focusto(9); errflag = false; msg=" '试题内容' 呢"
ElseIf Len(Trim(luru.A.value)) = 0 Then
focusto(10); errflag = false; msg=" '答案_A' 呢"
┋ ┋ ┋
ElseIf Len(Trim(luru.F.value)) = 0 Then
focusto(15); errflag = false; msg="请还原成默认值"
End if
If (errflag = false) then
msg = msg & vbCRLF
MsgBox msg, 64, "提示"
Exit Function
End if
datacheck = errflag; luru.Submit
End Function

八、后记
此系统从研究设计到投入实际应用历时4个月之余，通过多次细致的测试及鉴定，证明系统完全具有可行性与可扩充性，就最近传来的消息，该系统获得了湖南省科技厅的普遍好评。另外，系统还有待于进一步升级，并将实现试卷的主观题部分和多媒体试卷。因此，仍有大量的工作需要开展。若有不详或不妥之处，请您以应用程序为准以及提出良好的意见与建议。
