Subject:	windows exit codes truncated to 1 Byte
MIME-Version:	1.0
References:	<1233154500 DOT 205789 DOT 1459429282664 DOT JavaMail DOT yahoo DOT ref AT mail DOT yahoo DOT com>

I noted that exit codes returned by CMD and other apps (msiexec) are truncated to 1 byte (0 .. 255).

Steps to reproduce:

1) Create a batch with this content:
$ cat ./test.bat 
@echo off 
rem ==================== 
echo Test exit code 266 
exit /B 266 
rem ==================== 

2) run the batch file:
$ ./test.bat 
Test exit code 266 

3) check exit code
$ echo $? 
10 


I would expect 266 but I got 10 instead. I checked for other codes and the result is the same. 
Windows exit codes are represented using 32 bits, so is this limitation intentional?


Best regards,
Cristi
