Hi,
I tried this:
I expected
5,5 as result, on the contrary Livecode result is
2,5,3 .
Why?

Hi Max,
sorry, but as a long time LC user I am asking myself, why you are exspecting 5,5?
The addition seem correct behavior to me:
A comma delimited list with an addition in the middle.
Did you enter this into the message box?
Without any command? Hmmm
In any way this is not how Liveocde works, you will need to add the ITEMS of the points separately.
Best

Yes, I understood.
I tried also:
but I can't act on points directly.
There are some features that I'd like introduced on Livecode:
- working directly on point and rect
- working on date and time directly (12/Mar/2013 + 1 = 13/Mar/2013; 3:02 + 1:00 = 4:02)
On rebol language is a standard, and now rebol is open source, rebol it's in C and C++ like LiveCode, so an inclusion of these features could be possible.

Exactly!

You can use "dateitems" to work with time and dates (almost) directly!

No idea about Rebol

you can create a custom function to do this. something like:
Code: Select all
function addPoints firstPoint secondPoint
add the first item of firstPoint to the first item of secondPoint
add the second item of firstPoint to the second item of secondPoint
return secondPoint
end addPoints

Klaus, you can laugh... but that is what I thought the poster was trying to figure out... but I did get bored when the 'old chesnut' of comparing what 'liveCode' does, or does not do compared to some 'other' language reared its ugly head...

LOL.
Your message contains 4 characters. The minimum number of characters you need to enter is 10.

@MaxV- I'm curious about what you expect to get if you add two points together.
Another point?
Is the second set of coordinates supposed to be an offset to the first set?
If that's the case, what would you expect for a rectangle? (100,200,200,300) + (3,3) = ?
I think there's a limit to the guessing that the parser can do with the input it's given.

Nothing, type mismatch.

Well, it's my fault; I was used with this:
Code: Select all
type? 2x5 = point!
type? 125.212.101 = color! (rgb format)
type? 2/3/2103 = date!
type? "hello" = string!
type? 20.30.150.200 = rect!
type? 10:20 = time!
# operations
2x2 + 3 = 5x5
2x2 + 3x4 = 5x6
150.3.200 + 1 = 151.4.201
151.3.200 + 10.25.37 = 161.28.237
2/3/2013 + 35 = 6-Apr-2013

However I'm sorry, I didn't want start a war
LangA is better than
LangB.
I prefer LiveCode, absolutely. Rebol was definitely abandoned in 12/12/2012. If LiveCode developers are interested to take some nice feature, sources and examples are here:
