SYNTAX Error in Battleship

Hi and thanks for taking time and helping me out. I am writing a program to play Battleship in TI-BASIC. It's an amateuristic program, so don't judge me on my bad thinking or anything. I am from the Netherlands, so don't judge me on my English either Very Happy

On to the program: I have put this BETA version on my TI84+, but it had an SYNTAX error in the last line, line 74 (End command). It somehow won't work, but I don't know why. It would be great if you could help me, so I can go on with my program. Thank you in advance.


Code:
ClrHome
Disp "PASSWORD","PLAYER 1","4 NUMBERS"
Prompt P
[[0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0]]->[A]

Pause

End
Lbl AD
Y-1->Y
1->[A](X,Y)
Pt-On(X-.5,Y-.5)
Pause

End
Lbl AL

Pause

End
Which control structure is the End supposed to be Ending? You don't need one just to exit the program.
<- Please Support on Lego Ideas
No, it's only part of the game. It is supposed to end the Repeat N=17. After this, player 2 has to lay down his ships.
Okay, you only have 1 item that requires End, and you have multiple Ends. So that is going to cause some issues. Also, Menu (and Goto) inside a loop is a bad idea, creates a memory leak, so that'd be something you'd want to change.

So, basically, any time you have a Repeat, While, For( or If:Then, you just use one End command per. Otherwise, the calculator will throw the error, because it runs across the End, but it doesn't have anything to show calling for the End.
Oh I get it. That was pretty dumb indeed. Thank you!
Not a problem. Smile

Might I recommend, you have a list of Horizontal and Vertical. You can shorten that with a For( loop

For(F,1,10
Horizontal F
End

If you want any help with getting away from the Menu and Lbl stuff to use loops, I'm sure we can direct you towards some code that will help you out. Or a good book.
