Hello.  Yes, we encountered the same problem and had to modify a homegrown
COBOL application.  Here are the comments taken from the code:

  2.6   *+  JFB (BEECHGLEN DEVELOPMENT, INC.) 04/29/1998  - Modified to
  2.7   *+        adjust to different FTP output under 5.5 powerpatch 4.
  2.8   *+       No longer is 'Transfer complete' or such received.  Also,
  2.9   *+       found that use of 'ascii' FTP command causes record
  3     *+       transfer truncation (only 1 record gets sent)-so removed
  3.1   *+       the 'ascii' command.  Took from v1.0 to v1.1 this date.

In pre PP4 we just checked for the 'Transfer complete' message to determine
if we successfully transferred a file.  In post PP4, where this message is
no longer being provided, we first make an estimate of the number of bytes
in the file being transferred.  We then determine a successful transfer to
be the case of when the number of bytes sent (as indicated in an FTP
message still being output) equals or exceeds the estimate.
