This is the form of path returned by MetaCard. Up to and including 
1.9.6 VXCMD.DLL happily accepted this path. It must have been converted 
internally in the DLL to the windows path  D:\fff\ddd\gg.vdb.  
Presumably this conversion no longer occurs with 1.9.7.

If I change NativePath() to replace / with \ (for VXCMD.DLL versions > 
1.9.6) it works. This should be safe since one Windows explorer wont 
allow  entry of / in filenames.

As to the problem of file corruptions involving SELECT statements, I 
can't yet comment.

However the following sequence that works perfectly with VXCMD.DLL 
1.9.6 now returns rubbish.

1. Write (approx 57000 bytes) binary data to Fixed Binary field FixBin 
using Binary_WriteData and Cursor_AddRecord
2. Select Fixed Binary method of table ie encode(FixBin,'ABC')
3. Read binary data from method using Binary_ReadData. Result is now 
truncated at 11 characters.
