I have written the following line in a batch script

set KEYWORD = 0x4000|0x200

and when I run it, it says

0x200 is not recognized as internal or external command

Please help me to do a bitwise OR of two hexadecimal numbers using a batch script.

Some examples of how to:

set /a "KEYWORD = 0x4000 | 0x200"
set /a "KEYWORD = 0x4000 ^ 0x200"
set /a "KEYWORD = 0x4000 & 0x200"

The double quotes are important, else it will be seen as cmd.exe operators and not as part of the set /a command.
