PowerPCB导入asc文件的问题

件：Orcad 9，Powerpcb 5.使用PowerPCB导入asc文件时，弹出对话框显示：
warning:improper data found in ****.asc may be ignored.
powerpcb.rep内容为：
======================================================================
Database Integrity Test Report on file Untitled -- Thu Oct 01 21:53:21 2009
======================================================================
WARNING: Color is specified for signal N42353, but the signal isn't in view list
CORRECTION: The signal will be included in view list
WARNING: Color is specified for signal N50125, but the signal isn't in view list
CORRECTION: The signal will be included in view list
WARNING: Color is specified for signal N45567, but the signal isn't in view list
CORRECTION: The signal will be included in view list。
PCB中警告提到的3个网络均以其他颜色显示。请问这个警告什么意思？
ascii.err内容为：
Reading file --***.asc
*Unspecified or unsupported version of ASCII file
*pads2000*
**INPUT WARNINGS FOUND**
请问这个警告如何消除呢？
谢谢！

ORCAD原理图中，此三个网络被设置了color规则。
可以忽略，继续进行

真强，再请教一下：
Reading file --***.asc
*Unspecified or unsupported version of ASCII file
*PADS2000*
**INPUT WARNINGS FOUND**
这个警告可以忽略吗？请问这个警告如何消除呢？
谢谢！

1，可以忽略.
2，将asc的前面两行改为：
！PADS-POWERPCB-V3.0-MILS！ DESIGN DATABASE ASCII FILE 2.0
*PART* ITEMS

试了一下，果然warning没有了，太强了，多谢！
论坛有和众多人气在，不没有解决不了的问题了。

大婶实在是威武
