7-Zip 7z.exe ERRORLEVEL Codes
A free file archiver for extremely high compression

I have been unable to find an authoritative reference for ERRORLEVEL codes for 7z.exe, the command-line version of 7-Zip.
All I have been able to find are examples of %ERRORLEVEL% statements scattered across the net.
Will somebody on the design team PLEAZE post this? It would be nice if it was in the docs or viewable by command line (e.g. >7z c).
For the record I have cobbled together these examples:
Code / Meaning
0 / No error
1 / Warning (Non fatal error(s)). For example, one or more files were locked by some other application, so they were not compressed.
2 / Fatal error
3 / change identified (does this indicate a change in the archive file itself or a difference when comparing archive file contents to the original source?)
7 / Command line error
8 / Not enough memory for operation
255 / User stopped the process
Igor pointed out the "Exit Codes" section of the help file. It does not contain ALL of the errorlevel codes.
I am getting an errorlevel 3 that is undocumented. It appears to be the result of testing a file that has been updated since its initial creation.
Again, will somebody please post documentation of all errorlevel/exit codes?
Download the source code, do a grep for exit, find a value, grep for that, find that ExitCode.h contains it all: (grep can ber optained several ways, I prefer services for Unix, but some smaller downloads should be available as well)
kSuccess = 0, // Successful operation
kWarning = 1, // Non fatal error(s) occurred
kFatalError = 2, // A fatal error occurred
// kCRCError = 3, // A CRC error occurred when unpacking
// kLockedArchive = 4, // Attempt to modify an archive previously locked
// kWriteError = 5, // Write to disk error
// kOpenError = 6, // Open file error
kUserError = 7, // Command line option error
kMemoryError = 8, // Not enough memory for operation
// kCreateFileError = 9, // Create file error
kUserBreak = 255 // User stopped the process
(From latest source, note that several codes are commented out)
