So I was messing around w/ my TI-83+ yesterday and had lowercase on, and I thought, "What if I put all the single Texas Instruments ASCII chars that are possible to type into Str1, in order?" I made a really simple program to do it, and whenever I typed in Str1 and hit [ENTER], it worked perfectly. Everything showed up as it should.
However, when I did the Shift+[RCL] function with Str1, I noticed something was odd about the first four characters. Instead of displaying:
"nuvw
, it displayed:
"nuvpov(
. And it only got more weird. When I moved the cursor up to the top, it changed to:
ClrHomefPart(nuvw"uvw
And whenever you press [CLEAR] it resets the cursor to line 1, column 8, and it will actually accept commands there.
I tried it multiple times, and it kept happening the same way. Whenever you press [ENTER], it sets the first few characters to:
ClrHomefPart(nuvwuvw
but if you press [CLEAR] from there, it resets to the normal position, at 1,1.
What I found most odd about it was that it actually changed the string from the initial form. In any case, I hope to do more research, but if you try something like it (but in a diff. order) you might get strange results as well. See what you can find!
