昨晚再重新建一個project and new .asm file
再將之前檔案內容copy至new .asm file，結果就找到耶！

看清楚點
Cannot open file (Include File "pl6f877.ASM" not found)
他是說 .asm 沒有找到
不是 .inc 沒有找到
看看有沒有設定錯路徑或是打錯字吧

在程式一開始，使用16f877的標準定義檔方式如下：
list p=16f877
#include <p16f877.inc>

經build all後!秀出結果如下:

我想應該是沒有順利載入定義檔所造成，檢查定義檔放置路徑應該沒有錯，但為什麼編譯器卻說沒有找到p16f877呢？

p16f877.inc放置路徑如下:
C:\Program Files\Microchip\MPASM Suite

此一問題，請各位大大指導!
