Problem with FTP_GET, FTP_BINARY when downloading mixed file types

["Henrico, Pieter" <Pieter.Henrico@xxxxxxxxxxxx>]

   Hi



   I have used the FTPAPI to write an application that basically does the
   following:



   1. Link to a remote server

   2. Pull down a list of all files using a specified filename selection
   (eg File*.*)

   3. Start working through the list:



   a. ASCII Data

   - If the file is a .TXT file, set the mode to ASCII

   - Download the file directly into the library
   (/QSYS.LIB/LIBRARY.LIB/FILENAME.FILE/FILENAME.MBR)

   - Submit a post-processing job over the downloaded file



   b. BINARY DATA

   - If the file is a zip file, set the mode to BINARY

   - Download the file into the IFS (/tmp/zip/filename.zip)

   - Unzip the downloaded file to a temporary space in the IFS

   - For each file inside the ZIP file:

   --- Create an empty PF inside the library

   --- Use CPYTOIMPF to get the data into the PF inside the library

   --- Submit the post-processing job over the file PF inside the library



   c. If the previous steps were fine, delete the file on the remote FTP
   server

   d. Loop again



   The problem is that if the program ONLY pulls down .txt files, or ONLY
   .zip files, the process works correctly.  However, the moment that the
   program has to download both .ZIP and .TXT files, things tend to
   break.  The files are downloaded, but the ZIP files are corrupt, and
   do not want to unzip (the text files are fine).  If the program only
   downloads ZIP files, the unzip function work correctly.



   I have done a low-level debug on the process, and I can see that the
   FTP server does respond with a code 200 (Type set to I) when doing the
   ZIP files.  However, the binary transfer is clearly not working
   correctly.  I also thought that the problem might be actually related
   to the FTP server itself, and has done these steps manually using
   normal FTP, but then the unzip function works correctly (currently on
   V6R1 for the OS).



   Does anybody have a similar experience, and any idea on how to resolve
   this?



   Thanks



   Pieter
