+Today's biggest accomplishment (for my December Adventure) was a successful
+refactor of last night's code. My string drawing implementation doesn't rely on
+the zero page anymore; everything happens on the working stack.
+
+Having to think about bytes vs. shorts is one way that uxntal differs from the
+other stack-oriented language I've been exploring lately,  [PostScript]({{< ref
+"posts/postscript-graph-paper/index.md">}}). At one point, I zero-padded a byte
+so that I could do a stack rotation on shorts cleanly, but I'm not sure if that
+was the best approach.
+
+The "obvious" next thing to do is to start reading keyboard input and echoing it
+to the screen. This is all such a tiny part of the program I'm hoping to finish
+(a "game" to help me learn Morse Code), but I only noodled a bit with that
+before losing steam for the night. TGIF.
