Ok, I am working on a scrolling-shooter-style game for the TI-83+. I am making progress, but I have run into a little snag. That snag is that somewhere in the program(s) the ram is being used up every time that part of the program is being excecuted. The way I know this is that every time an asteroid (theta) falls down, the program runs a little slower. I was wondering if anyone could see if they could find that place. Here is the code for the three programs in the game,

Here is a .zip file attached below containing all three BASIC programs
EDIT: I removed the attachment because This problem has been solved, and there's no need for people to bownload this incomplete version

Here is the code itself

Menu (the menu)

Code:

//PrgmMENU
ClrHome
Output(1,4,"SPACEFIGHT
Pause
Goto MN
Lbl MN
Menu("   Spacefight      ","Play",PY,"Help",HP,"Quit",QT
Lbl PY
prgmINIT
Stop
Lbl HP
ClrHome
Output(1,1,"HELP
Pause
Goto MN
Lbl QT
ClrDraw
ClrHome
Stop


init(the initialization script)

Code:

//PgrmINIT
ClrHome
ClrDraw
Output(1,1,"INITIALIZING...
Xmin
94->Xmax
1->Xscl
0->Ymin
62->Ymax
1->Yscl
1->Xres
CoordOff
GridOff
AxesOff
LabelOff
ExprOn
47->X
8->Q
randInt(6,67)->R
ClrHome
ClrDraw
prgmGAME
Stop


game(the actual game).

Code:

//PgrmGAME
Text(57,X,"^
Lbl A
While 1
getKey->K
If K=24 and X>7
X-4->X
Text(57,X,"^
Text(57,X+4,"   "
If K=26 and X<87
X+4->X
Text(57,X,"^"
Text(57,X-7,"      "
If K=21
Line(X+1,5,X+1,62
Line(X+1,5,X+1,62,0
Goto B
Lbl B
If Q>55
Then
Text(Q,R,"   "
5->Q
randInt(6,87)->R
Goto C
End
Lbl C
Q+4->Q
Text(Q,R,"Á"
Text(Q-5,R,"   "
Goto A


I know that this game is far from finished, but I just uploaded the game as-is, it is run-able

What's with all the labels in the main game code?

First of all, this is useless:

Code:
Goto B
Lbl B


Second, this is useless and causes a memory leak:

Code:
Goto C
End
Lbl C

Just use an End by itself.

Third:

Code:
Lbl A
While 1
...
Goto A

This causes another memory leak. Use this instead:


Code:
While 1
...
End
