TI-BASIC / Detecting/controlling homescreen clears?
« on: September 10, 2011, 05:45:45 pm »
So, I've written a joke program that imitates the homescreen, but outputs Fish for 2+2. This is it:
It works perfectly, except for one critical bug: if you press CLEAR, the line counter for the word FISH isn't updated, and it will display it in the wrong place.
So my question is, is there a way to detect if the homescreen is cleared, or if I can control that? Or is there a better way to display FISH than Output()?
Thanks!
Code: [Select]
2→A
ClrHome
While 1
Input "",Str1
If Str1="2+2"
Then
Output(A,13,"FISH")
Disp ""
Else
Disp expr(Str1
End
If A<8
Then
A+2→A
End
End
It works perfectly, except for one critical bug: if you press CLEAR, the line counter for the word FISH isn't updated, and it will display it in the wrong place.
So my question is, is there a way to detect if the homescreen is cleared, or if I can control that? Or is there a better way to display FISH than Output()?
