为什么这个程序可以编译通过，可是最后的EXE文件却不能运行？我也试过了其它的程序，有好多都 是可以编译通过，但不能打开运行的？请问有没有高手知道这是为什么？谢谢

Category: D - DOS kernel

Inp.:
AH = 3Ch
CX = file attributes (see #01378)
DS:DX -> ASCIZ filename
Return: CF clear if successful
AX = file handle
CF set on error
AX = error code (03h,04h,05h) (see #01657 at AH=59h/BX=0000h)
Notes: if a file with the given name exists, it is truncated to zero length
under the FlashTek X-32 DOS extender, the pointer is in DS:EDX
DR DOS checks the system password or explicitly supplied password at

the end of the filename against the reserved field in the directory
entry before allowing access

不能运行。。不知道会不会是连接成PE格式，所以才不行。。。
