IIRC it is only the older manuals (pre-4.20) that have the error codes, and they are the English language versions.

Printing them yourself will give you the installed language version, and makes searching for something appropriate much easier.

Here is a more useful example. When prompted, supply an error number to display or a string to search for a matching error:
Code:
Break ON
$=SetOption("WrapAtEOL","ON")
$=SetOption("ASCII","ON")
 
"Enter an error code / string or null to exit: " GetS $s
While $s
	If CStr(Val($s))=CStr($s)
		$=Execute("Exit "+$s)
		@ERROR " : " @SERROR @CRLF
	Else
		$iLine=0
		For $iError = 0 to 9999
			$=Execute("Exit "+$iError)
			If Not InStr(@SERROR,"(317 / 13D)")
				If InStr(@SERROR,$s)
					@ERROR " : " @SERROR @CRLF
					$iLine=$iLine+1
					If Not ($iLine MOD 20)
						"Hit a key for next page or 'x' to exit search: " Get $k
						Chr(13) "                       " Chr(13)
						If $k="x" $iERROR=9999 EndIf
					EndIf
				EndIf
			EndIf
		Next
		If Not $iLine "No error strings matched." @CRLF EndIf
	EndIf
	"Enter an error code / string or null to exit: " GetS $s
Loop
 
Exit 0
