I just started learning BatLib Basic and loved it (when I read the pdf) and now found an error, I guess:

Code: [Select]
dim(22,"EF0745
Prompt A

It prompts for var A, but the screen is not cleared :S

And I run this:

I just started learning BatLib Basic and loved it (when I read the pdf) and now found an error, I guess:

Code: [Select]
dim(22,"EF0745

It'll print EF075.

Any idea of what I'm doing wrong? Thanks.

The hex code to clear the LCD is EF4045 :P
All that does is clear the LCD, but when displaying the homescreen, it will reload the contents from the buffer
EF0745 displays the current contents of HL, but if you run it from the homescreen, the string is displayed, overwriting the value. So, in a program you can do:
Code: [Select]
dim(22,"EF0745
Pause
That being said, I have been bugged about this, too, but since I wasn't sure if anybody else would be, I decided to leave it this way. It will only take 4 more bytes of code, but I can prevent dim(22 and dim(23 from modifying Ans. Are there any other commands that should not modify Ans?

That worked fine for me... I just tested it. Is that the only code?

I had to reparse hooks, it worked, but it displays a 5 in the right part of the screen :S

OH WAIT, that's the variable A

Might I ask what the value for A is XD
EDIT: Never mind :P

Now I want to know if when I create a rectangle, I need to dim(99) to see it. Thanks.

I tried this:

Code: [Select]
ClrDraw
ClrHome
dim(29,0,30,0,30
dim(99

And got no success.

Wait, I didn't put a type, 1 for black worked :D

EDIT:
My first cool thing:
Code: [Select]
dim(2
dim(22,"FDCB00AE
dim(22,"EF4045
dim(29,0,96,0,64,1
dim(99
Pause
:D

Cool! I love the rectangles ♥ Um, my most common error is that I forget to add a type. But anywho, I want to give you an optimisation trick that might be tough to grasp:
Code: [Select]
dim(29,0,8,0,8,2      ;makes an inverted 8x8 rectangle at (0,0)
dim(99                ;Displays the graph screen
dim(10,67             ;This waits for a key press in the arrows, Enter through Clear, and Graph through Y=, and 2nd to Del
dim(43→A              ;This returns a key press that detects up to 2 keys
dim(29,0,8,0,8,2      ;makes an inverted 8x8 rectangle at (0,0)
However, if you want to speed up the code a little as well save memory, you can combine all of the syntaxes:
Code: [Select]
dim(29,0,8,0,8,2,99,10,67,43,29,0,8,0,8,2→A
Both of those will invert a rectangle, display the graph, wait for a keypress, reinvert the rectangle, and then store the keypress to A
The optimised method might be more difficult to read later, though :D

EDIT: Hehe, that is the same mistake I make most often :D By leaving off the 1, it was read as 0, so it cleared the rectangle XD

Niiice Xeda, thanks :D

Code: [Select]
dim(2
dim(22,"FDCB00AE
dim(22,"EF4045
dim(29,0,96,0,64,1
dim(99
Pause

As I said, this code is OK, but closing it is hard and the screen isn't cleared in the end. Any idea?

You need to clear the textShadow buffer, too, so you can use EF4645. So, dim(22,"FDCB00AEEF4645

Ah thanks much :D

HELLO WORLD:

Code: [Select]
AxesOff
ClrDraw
dim(87,5,5,"HELLO WORLD
dim(99

It's a very ugly Hello World though.

Actually, what I get is:

HELLO)WORLD
                   99

In the screen, the ')' and the 99 are weird :S

Hehe, that is because that displays ASCII data :P Check command 90 :D

That is because it doesn't actually tell the calc you are looking at the graph screen, it just displays it, even if you are on the homescreen. Try putting a pause there :)

Perfect, I put the coordenates as (5,5) but it appears quite far from (5,5). It looks like 5,20. (I'm always talking in (Y,X)).
