winSCP returned with File does not exist: error code 2

I have been running WinSCP in scripting mode from a Windows batch file on a Windows 2003 server. I got into a situation where the Put operation complained about not finding the file to transfer, but I still did not get any Windows level error code back.

As you see, the log file had an error code, but it did not get propagated onto the Windows batch file level.
The same script was properly running (returning no error code with successful run, returning error code with failed run) on the same server like about 60 times previously.
I would appreciate if you could reply ASAP.

Thanks,

So are you able to reproduce the problem with error code? If you are I can send you a debug version. Btw, how do you check for error code?

In the batch file executing the WinSCP script, there is the following line:

IF %ErrorLevel% GTR 0 (
SET Errmsg="Failed to FTP File"
GOTO ERROR
)

On further investigation, I have realized that some Windows level errors (e.g. probably file does not exist) are returned with negative code. The Windows script fragment above does not catch negative error codes.

In order to catch negative error codes, I changed the above test to
IF %ErrorLevel% NEQ 0 (
SET Errmsg="Failed to FTP File"
GOTO ERROR
)

Looks OK.
WinSCP returns only 0 (on success) or 1 (on error).
Can you post your script and command you use to run WinSCP.
