I am trying to create a simple BASIC program for my TI-84 that will calculate the midpoint of two given points. This is my current code below, which produces an error upon trying to run the program:
:Prompt XONE,YONE,XTWO,YTWO
:((XONE+YONE)/2)->X
:((XTWO+YTWO)/2)->Y
:Disp X,Y
The reason I suspect it has something to do with my variable naming is because I tried running the same program, except I named the variables A,B,C, and D, instead of what you see above, and that ran fine.
