Hi,
I am working with Mma 2.1 on PC (Win 3.1) and have some problems with
OpenWrite[...]:
MMa seems to be unable to decide, wether 2 different strings lead to
different filenames or not. 
Example:
In[1]:= OpenWrite["Mathematica.txt"];
In[2]:= OPenWrite["Mathematica.txt"]
Out[2]= $Failed (* correct *)
In[3]:= OpenWrite["Mathematic.txt]
Out[3]= OutputStream[.....]  (* not really correct, because both opened
                                streams are in fact identical *)

One could write a simple Mma function which solves that problem for PC's by
truncating and "UpCaseing" all filenames. But, is there a simpler way to
decide, wether 2 strings lead to different files on the system one is
currently working? I mean a way not using my knowledge about the filenames
conventions of my computer.

Thanks for Your comments!
