I am using Windows Batch Texts to automatically run FTP scripts. Usually the set of commands I want to control is stored in a file.

  @echo off -dftp -i -s: c:  temp  myfileftpscript.ftp 

I have used the actual% ERRORLEVEL% syntax to successfully capture error conditions during batch commands. My problem must be that the FTP script command always returns an ERRORLEVEL value of 0 even if the script statements fail.

I am still having trouble understanding how the File Transfer Protocol returns or intercepts a script on failure. It will only execute pass-through commands blindly and far away, although I see misunderstandings on the screen, I cannot save them as ERRORLEVEL ..

Example screenshot of attempted story that doesn’t match and reflects well sya, then ERRORLEVEL, which shows zero ..
