I like that!
I like the multiblock if statements, and then this works good for single statements.
Can't wait for more updates!

Oh yeah! The Ternary operator! ^^ I remember that from Java and its lots of fun, especialy because its like an if statement that can be used in expressions :D

Oh and I'd like some feedback on this: Should I continue to exclusively use multiblock "If" statements?  Or should I do what BASIC does and allow single or multiblock?  The disadvantage is that then you would have to add the token "Then" after every multiblock statement.  The compiled program will be the same either way, but what is more convenient, never needing the "Then", or sometimes not needing the "End"?
I'd keep it how it is now.  I don't like using all the ":Then"s that must be used in Ti Basic.

I've never heard of the Ternary operator.  It looks really cool, though. ;D
Side note: This is my 800th post. =)

Btw in TI-BASIC it's

If <Condition>
Then
<code>
Else
<code>
End

not

If <Condition>
<code>
Else
<code>
End

And you can also do

If <Condition>
Then
<code>
End

However I am lost now. I am a bit confused by that feature request, because it contains a lot of terms I never heard before, programming-wise. Are people implying that the ability to use multiple lines of codes inside If blocks will not be possible in Axe or the opposite?

it would suck to have to do like on the TI-81:

If A=1
<first code to run if condition is true>
If A=1
<2nd code to run if condition is true>
If A=1
<3rd code to run if condition is true>
If A=1
<4th code to run if condition is true>

or the opposite, having to do

If A=1
Then
D->B
End

instead of

If A=1
D->B

Single line expressions can be executed by using the ternary.  In your example, you could either do it with blocks like this:

If A=1
D->B
End

or, because its a single expression, do this:

A=1?(D->B)

which is more compact than the regular TI basic.  I don't think I will use the "Then" token at all, maybe I'll re-code it do something else in the future.

Sounds great!  I'm liking the more that I see of the ternary operator. ;D

Indeed.   Mmmmm another question, are Boolean expressions going to be evaluated with short circuit evaluation?  For example withe if(A and B) if A is false, the program doesn't event bother to test B, and with if(A or B) if A is true you wouldn't need to evaluate B either.  I know java has this implemented, and was wondering how it is set up now.

Hmm, I was wondering, could Celtic III style program control be added? So like, calling another program, getting a list of programs, creating a program, deleting a program, etc.
Also are you planning in adding string operators? Like sub() inString() and such?

not sure, I think he only planned most pure-basic commands

Its too soon to tell.  I'm not sure if I will have commands for program manipulation, but there will definitely be a way to create, save, and load application variables.

String handling is going to be very different since all strings are constant length.  It is very easy to get a substring if it ends at the normal ending, you can just do Disp Str1+A.  For anything else, you can write your own subroutine to copy part of the string to a buffer and then display the buffer instead of the string.  I can probably automate this but I would use a different command instead of sub().  Its still faster than the TI-BASIC sub() command.

ah ok, hmm, interesting... Automated would be nice... Of course that isn't a priority right now.

can strings be used in a way that they can be tilemaps like some people do in TI-BASIC? See Illusiat 13 for an example. Illusiat 13 maps are  128 chars long each, btw, which fills the entire home screen

Data is data.  String = Picture = List = Hex.  It also equals executable code, but that part is my job  ;)

You can use strings however you like.  You would probably use decimal numbers or hex code for a tile map, but if its more convenient, then yes you can use a string as well.

Ah ok. What I like with strings is if we use ASCII maps (or dual layer like in Serenity/Elmgon, assuming we use Storepic/Recallpic too), is that each map rows are drawn almost instantly. Maybe with Axe, doing so with sprites won't make much of a speed difference anymore, though, since TI's text display routines are slow by nature compared to a third-party sprite routines :P
