If/Then
What is If and what is Then?
If and Then are commands that tell the calculator when to do something, and what to do. It is simple.
A completed If and If/Then command might look like this:
If A=5
or
If A=7
If is used to show that you want whatever you program next to accure when the statement happens. Such as, 'when A=5, do this...'
If A=9
'Then' would work when more then one thing happens, like:
If A=4
Notice how I used End at the end of every 'Then' statement. You must have this or the program will mess up and quit.
randint(1,4)->A
This choses a random number from 1 to 4, and displays text corrosponding to whichever number is chosen. Simply, isn't it? Again, notice how I used "Then" and "End" when I had to place two text messages.

End
However, if you want more than one thing to happen, like if A=5 and you want three things to occur, you need to use the "Then" command. "If" (by itself) is used when you only want one thing to happen. Like:
Output(5,7,"Hi
Then
Output(4,1,"Hi
Output(3,1,"There
End
If you want to make a simple fortune teller program, you can use the If/Then statements. Below is a sample fortune program.
If A=1
Disp "Yes
If A=2
Disp "No
If A=3
Disp "Maybe
If A=4
Then
Output(1,1,"Could
Output(2,1,"Happen
End
