hmmm, I also just program on the TI-83 Plus but...I'll try not to be technical
ok, so you want to retain the previous selection...here we go then
Try this (in psuedocode since i havent programmer 89's):
( -> denotes that value is being stored to variable aka 1->A places the value 1 into A)
[beginCode]
...The first line of your programs initialize (declare your variables set to 0)...
...begining of program...
0->prevchoice
0->choice
...somewhere else in the program...
choice->prevchoice
0->choice
Dialog
Title "The Ultimate Pre-Calculus Program"
DropDown "Calculate:",{"Area of ","Comp Angles","DegreeğRadian","Grade","Find Quadrant","sin, cos, etc.","Distance"},choice
EndDlog
...i modified this part...
if choice=0 Then
prevchoice->choice
goto quit
ElseIf feat=1 Then
Goto a
ElseIf feat=2 Then
Goto comang
ElseIf feat=3 Then
Goto dtr
ElseIf feat=4 Then
Goto grade
ElseIf feat=5 Then
Goto quad
ElseIf feat=6 Then
Goto sct
ElseIf feat=7 Then
Goto dist
EndIf
[endCode]
I dont know if that will work, but just maybe..... get back with me on the results
