市场部年度总结报告:朋友们,能替我解释下这段ASP代码的意思吗？小弟不胜感激

If (CStr(Request("MM_insert")) = "form") Then

MM_editConnection = MM_conn_STRING

' create the MM_fields and MM_columns arrays
MM_fields = Split(MM_fieldsStr, "|")
MM_columns = Split(MM_columnsStr, "|")

' set the form values
For MM_i = LBound(MM_fields) To UBound(MM_fields) Step 2
MM_fields(MM_i+1) = CStr(Request.Form(MM_fields(MM_i)))
Next
