nndstojmp is short for nand, store, jump. It is an OISC that takes 4 parameters. Parameters a and b are the 2 memory bytes which are nanded and the result is stored in memory location c. After this, you jump to memory location d. Location 0 in a or b is input, in c is output, and in d is end program.

Instructions

Given the instruction pattern

a b c d

the effect of parameter values can be summarized in the following:

Parameter	Effect if zero	Effect if non-zero
a	Contributes the left NAND operand as the byte at the memory location a.	Queries the user for a byte as the left NAND operand.
b	Contributes the right NAND operand as the byte at the memory location b.	Queries the user for a byte as the right NAND operand.
c	Stores the NAND-combined a and b bytes in the memory location c.	Prints to the standard output the NAND-combined a and b bytes.
d	Moves the memory pointer to the memory location d.	Halts the program immediately.

Examples

Hello, World!

This program outputs the ASCII character codes comprising the message “Hello, World!”

Interactive NAND

The following program repeatedly queries the user for two bytes, which are subsequently NAND-combined, ere the result is printed to the standard output.
