Okay, so I want to make a program that calculates area based on dimensions given. However, there is no 1 universal formula for area, so I wanted to make a menu.


Code:

:MENU("SELECT A SHAPE","SQUARE",1,"TRIANGLE",2,"CIRCLE",3,"ETC...
:If 1, Then
:INPUT "LENGTH "→L
:INPUT "HEIGHT"→H
:INPUT "IF 3D, WIDTH"→W
:LWH

...and so on?

The menu syntax is Menu(Title,Option1,Label1,...
So the program should look like this:


Code:
:MENU("SELECT A SHAPE","SQUARE",LA,"TRIANGLE",LB,"CIRCLE",LC,"ETC... 
:Lbl LA
:...
:Lbl LB
:...

The numbers in the Menu( command should associate with labels in your code.

Code:
:Lbl 0
:MENU("SELECT A SHAPE","SQUARE",1,"TRIANGLE",2,"CIRCLE",3
:Lbl 1
:INPUT "LENGTH "→L
:INPUT "HEIGHT"→H
:INPUT "IF 3D, WIDTH"→W
:Pause LWH
:Goto 0
:Lbl 2
...

While we're picking on problems, That's not the proper syntax for Input. It's actually:


Code:
Input "STRING TO DISP",VAR

Input "LENGTH=",L

I finally realized about the wrong Syntax after about 4 errors.

I finally got the code:


Code:
PROGRAM:RegularPolygon
:INPUT "NUMBER OF SIDES=",N
:INPUT "LENGTH OF ANY ONE SIDE=",S
:DISP "AREA=",(S²N)/(4tan(π/N))


It works, but only for regular polygons.

I started a menu for different shapes that can't be solved with this, but it eventually threw me syntax errors.


Code:
PROGRAM:SHAPES
:Lbl 0
:MENU( "TRIANGLE",1,"SQUARE",2,"RECTANGLE",3,"CIRCLE(RADIUS)",4,"CIRLCE(DIAMETER),5, //I STOPPED THERE.
:Lbl 1
:INPUT "BASE=",A
:INPUT "HEIGHT=",B // I WANTED TO KEEP IT SIMPLE, NO NEED TO FIND FOR HEIGHT.
:DISP "AREA=",.5BH
:PAUSE
:Lbl 2
:INPUT "LENGTH=",A
:DISP "AREA=",A²
:PAUSE
:Lbl 3
:INPUT "LENGTH=",A
:INPUT "HEIGHT=",B
:DISP "AREA=",AB
:PAUSE
:Lbl 4
:INPUT "RADIUS=",R
:DISP "AREA=", πR²
:PAUSE
:Lbl 5
:INPUT "DIAMETER=",D
:DISP "AREA=",(π/4)*(D²)
:PAUSE

I'm assuming you're still using TI-BASIC; that uses "Lbl 1" etc instead of "L1". Sidebar: You know that SourceCoder can automagically grab text-formatted source code from your .8xp files, right? I just get a tad thrown by your TI-BASIC that appears to be formatted somewhat like QBASIC other than the missing line numbers.

I am still using TI-BASIC, and wow, that's quite possible.

I am aware of the fetching features of the fantastic tool, SourceCoder, however, I prefer to work on Notepad first, then plug or make the .8xp.

Thanks.

Sidenode: QBasic doesn't have line numbers Smile To add on to what Kerm said, if you use SourceCoder, it will be much easier to read than this shouting code you pasted. TI-Basic has tokens like Input (Note the casing) not INPUT. And, as Kerm said, too (Razz), TI-Basic uses Lbl (I can't think of any language that uses L only). You might be using lists just because the tokens looked close enough, but L1-L6 [2nd][1] through [2nd][6] aren't labels, they stand for List1 List2 List3, etc.

If you're just starting out with TI-Basic, I highly recommend that you do most of your coding on your calculator using its editor; it will help you test things faster and you can better understand what the commands do.

Heartily seconded. One of the best strengths of TI-BASIC is that since it's written on its target device and requires no compilation, the time between typing a line of code and testing it is nearly instantaneous, which provides for nice tight, fast debug/fix/debug/fix cycles. Smile

I think that's also what I did, _player.

souvik, I guess I should get in that habit. It's quite tedious, though.

Much less tedious than typing out every single command, plugging it into a converter, opening TI-(Dis)Connect, sending the program, and running it, surely? Compared, of course, to: open the TI-Basic editor, write code, run, repeat.

I certainly agree with you there, Catherine. Smile And of course the occasional TI-Connect -> SourceCoder -> Cemetech post when you get stuck with something. Smile

Souvik is 100% right. It's much better to do it on calc (as the 2 or 3 users before me said...)

Protip: Getting to know the shortcut numbers and letters for all the menus in your calc makes it WAY faster to program (and do other random tasks). It's kinda tedious to remember at first, but you'll get used to it Smile

for instance, when writing a basic program and you want to put a Lbl in, the keystrokes
[prgm] [9] [enter]

make the task WAY faster than
[prgm] [down] [down] [down] [down] [down] [down] [down] [down] [enter]

Just to make sure, when you try to write a BASIC program with the on-calc editor, you aren't typing the commands letter by letter, are you? (That's what I did when I first started programming my calc.... It made it preeeettty difficult to run my programs Laughing )

Hehe, that's always key, but I think he got that lesson by now. Wink At one point I was ridiculously skilled at both touch-typing strings and touch-typing commands without actually looking at what menus I was going into, but I'm afraid school and work have wrested that skill from my brain. Sad
