Some more optimizations:

2*A can be 2A (in the gambling part, right after the first "You Won" message)
Similarly for the other cases (3*A can be 3A, 4*C can be 4C, etc.)

After the line

Code: [Select]
Output(8,1,"< MODE IS QUIT >there is B+(K+26 and ... 0
The ending parenthesis can be omitted.

Before the message, "BETA TESTER!", the If statement

If LRNDM(1)=1

can be:

If LRNDM(1

The same applies to all similar cases.

Right after Lbl 3, 0 -> B can be DelVar B.

A little after the "All codes unlocked" message,

Repeat LRND(F+1)=0

can be

Repeat not(LRND(F+1

In general, closing parentheses and multiplication symbols should be omitted.
Also, if there is a conditional (If, While, etc.) that requires an expression equal to 1, the =1 part can be omitted. So,

If L=1

would become

If L

Although this isn't a speed-intensive game, isn't it true that 0-> is actually faster (although Delvar is smaller? (but only due to the fact that you can chain commands off of it))?

It probably doesn't make too much of a speed difference, since TI-Basic Developer suggests always using DelVar:

Also, if you want an optimisation trick, you can leave off the ending quote. Also, Disp commands can be on the same line. So:
Code: [Select]
Disp "HELLO"can be optimised to:
Code: [Select]
Disp "HELLO
i did know this one, but i may have done it sometimes...

And this:
Code: [Select]
Disp "HELLO"
Disp "WHAT IS"
Disp "YOUR NAME?"Can be:
Code: [Select]
Disp "HELLO","WHAT IS","YOUR NAME?
i think, that far in the back of my mind i knew it, but i forgot, it seems.

i just did that to be sure it worked ;)

i have never used the not( statement before, i'll experiment with it ;)

In general, closing parentheses and multiplication symbols should be omitted.
Also, if there is a conditional (If, While, etc.) that requires an expression equal to 1, the =1 part can be omitted. So,

If L=1

would become

If L

now your saying it wrong.
If L/=0
(does not equal)

would become

If L

because "If L" returns 1 if the variable exists


i'll wlak through my prog today and see what i can do with your tips :D

Well L=1 is basically a subset of L /=0 (a special case), but you're right.

If the only possible values of L are 1 or 0, then you can use If L instead of If L=1. However, if L can be 0, 1, or 2, you would have to use

If L=0
(code)
If L=1
(code)
If L=2
(code)

okay :D

i optimized it during school, but at the end of the day i used ARCHUNDEL and by accident i replaced the optimized version with the non-optimized...

Oh... sorry to hear  :(

It's good to get in the habit of backing up often, even if that means making a group on the calculator.

For optimizations, you can always go to the TI-Basic Developer: http://tibasicdev.wikidot.com/home

There is a lot of information there that I sometimes use.  :D

Try X=L1(1 instead, maybe?

WHAHAHA XD i hadn´t thought of that XD i feel so stupid right now...
lolz, thx XD

im just used to that. first the var, then the thing that it needs to equal,etc...

L1(1)=X can also be used, but it's one byte larger.
