• Logical operators (and, or, xor, not, masks, etc)
• Bit-wise operators (shift, rotate, rotate with carry, etc)
• 32 storage registers
• 4 position stack
• 203 lines of program memory
WRPN 16c is available on other platforms, such as Windows, MacOS, and Linux from the following web site http://www.wrpn.emmet-gray.com
