72进制转换

<%
'*******************************************************************************************
'把任何一个进制(不大于72)转换为另外一个不大于72的进制，字符由0123ABCXYZ[\]^_`abcdxyz{|}~组成。
'调用 T=DecTranTo(TranToDec(数,源进制),目标进制)
'举例:
' response.write DecTranTo(TranToDec("2147459999","10"),"36")  & "(结果是 ZIJIQN )<br>"
' response.write DecTranTo(TranToDec("2147483647","10"),"72")  & "(结果是 17x[Hn )<br>"
' response.write DecTranTo(TranToDec("000000X5Zm", 72 ), 10 )  & "(结果是 12345678 )<br>"
