DOS allows you to set an APPEND path to locate data files. Microsoft C
library functions such as open and fopen will not ignore the APPEND
statement, even if a full pathname is given to the specific function.
This is expected behavior. If you wish to have the APPEND path
ignored, you will have to write your own low-level open function, or
ensure that the APPEND path is removed before your program is run.
