Re: FTP 425 Error Code

[John McKee <jmmckee@xxxxxxxxxxxxxx>]

I have written code to retrieve data from VMS.  What I do is retrieve a 
list of
filesfrom the remote system and build a list of files to retrieve.  The files
on the VMS system are not identical file names as you show, but they differ by
only three characters, in addition to the file version number (portion
following the semicolon character).  So, I retrieve the files to 
generated file
names.  In the case of the files you show, the GET command I would use would
look like this:

GET ODATA345239.DAT;2538 QTEMP/R2538

For one thing you can't have  filename longer than 10 characters.  I 
also do not
think that a period is valid, but I am not near a system to verify that.

Hope this helps.
