Question

第一： 此代碼彙編不能打開，我進入它的名字

二文件： 我不知道如何合併此代碼，以我的代碼，我用它來打開文件

TITLE Reading a File (ReadFile.asm) 
            ; Opens, reads, and displays a text file using 
            ; procedures from Irvine32.lib.

BUFFER_SIZE = 5000 
.data 
buffer BYTE BUFFER_SIZE DUP(?) 
filename BYTE 80 DUP(0) 
fileHandle HANDLE ? 
.code

mWrite "File size: " 
call WriteDec        ; display file size 
call Crlf 
              ; Display the buffer.

quit: 
exit 
main ENDP 
END main

，如果你有，你想從驅動器C例如文件名應包含驅動器名讀取文件： 文件名必須是「C：\ anyFileName.txt」
