It then gets a single character from the user and writes it into the cells set as the low and high nybbles. The program eventually moves on until it meets the "comparing skip" operation. It normally moves steps in the current movement mode specified by the right cell if the byte to the left is nonzero. However, the sides got swapped earlier on in the program, so this actually skips 1 step to the left (because the program execution is facing left) if the right cell (the low nybble of user input) is nonzero. When it doesn't skip, it continues the program, but then tries to execute the space it's sitting on, but the space character isn't a valid hex character, so the program terminates. When it does skip, the program skips the space straight into a loop, where <code>7</code>, <code>8</code>, <code>9</code> and <code>6</code> is right, down, left, and up (respectfully) and <code>c</code> is the operation to print out an ASCII character formed out of the low and high byte. If the low nybble wouldn't have been specified, it always defaults to 0, so does an unset high nybble.', 22 => '', 23 => '[[Category:Two-dimensional languages]] [[Category:Languages]]' ]
