The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.

Problem: We FTP files from the i to a Windows server. On a few occasions,
we have had corruption even though FTP reports the transfer completed
successfully. The largest of these files have a record length of 2000
bytes, and have record counts approaching 3 million on some days.
Determining that corruption occurred often happens weeks later, after the
original source data is removed from the i.
The current thinking around here is to use a hash code. We already found a
few tools that can create a hash on the file that sits on the Windows
server. However, when I searched in the midrange.com archives, I found
several references to the QC3CALHA API. Unfortunately, it appears to be
limited to a data length that can be defined in Binary(4). I presume that
the data length would be the product of the record length and number of
records in the file.
I found another link in the archive that provided source code for an
application and that appears to use a stream file as input:

It's been too many years, but can a native library/file object name be
specified as a stream file?
Any advice would be greatly appreciated!
