Basically, you go to the PRGM button on your calculator, scroll over to NEW, and hit enter. Then you name it whatever you want. hitting the PRGM button allows you to access many tools. If, Then, Else, Goto, and Lbl allow you to make if-then statements. you do that like this
:If (this is an example) X=3
:Then
:Goto 9
:Else
:Goto 0
Then you have to make Labels 9 and 0, and have them do something. End and stop both end the program, but sometimes one works and the other deosn't. Pause halts the Program until the Enter button is pushed, but there are ways to create time delays. One way is to have a loop
:0->x
:Lbl 0
:X+1->X
:If X<15
:Then
:Goto 0
:Else goto 1
:Lbl 9
:whatever you want it to do now
The Menu button is one of the hardest things to work with, but one of the most helpful. You need a lot of labels typically. A sample menu is shown here.

:Output(2,1,"HI MY NAME IS JOE
will display
HI MY NAME IS JOE
ClrHome clears the home screen, and must be done before any output

EXEC only does another program within yourself
If you can't get out of anything, hit the 2nd off button, and it will turn off or display ERROR:BREAK
1:Quit
2:Goto
beware of loops such as
Lbl 9
blah blah blah
Goto 9
or
in the program HI
Prgm HI
Because it allows us to perform calculations that would be too difficult (or too slow).
