How to intercept Robocopy output?

[Freddis]

Hi everyone, I'm learning programming with AUTOIT. I've put four lines of code in it to perform backups with the Windows 10 "Robocopy" command. I intercept an ERROR string in the log file, but sometimes it gives false errors, definitely because I didn't write it well. For this reason, I'd like your help in learning how to intercept the error and the exit code well. I tried writing it with windows script commands and it seems to work fine and also with AUTOIT but I think you need to change the interception method. I'll put the scripts in there. Thanks to anyone who would like to help me.parzial.batparzial.au3

if %ERRORLEVEL% EQU 1 set ESITO=OK: File copiati correttamente
if %ERRORLEVEL% EQU 3 set ESITO=OK: File e cartelle copiate
if %ERRORLEVEL% EQU 8 set ESITO=OK: Backup ok, 1 file saltato - vedi percorso sopra
if %ERRORLEVEL% GEQ 9 set ESITO=ERRORE GRAVE: Backup fallito
