To all in this thread:

Just made an interesting discovery today:

DIFFERENCES

  Parameters

     

    input1-filespec

       Specifies the first file to be compared. The file specification
       must include a file name and a file type. The asterisk (*)  and
       the percent sign (%)  wildcard characters are not allowed.
     

    input2-filespec

       Specifies the second file to be compared. Unspecified fields
       default to the corresponding fields in the input1-filespec
       parameter. The asterisk (*)  and the percent sign (%) wildcard
       characters are not allowed.

       If you do not specify a secondary input file, the DIFFERENCES
       command uses the next lower version of the primary input file.
     


DIFFERENCES Subtopic? 

OK, no * or % in the params. But my example here only fails the first time you run it! Simply repeating the command, then it works fine. 

Well, it seems to only work if your input2-filespace is in the first subdir. So best not to use it.
