Absolute Definitions designed to introduce a built-in way to send data from the bottom of the Worksheet to it's top.Example: absoluteDefinitionsExample.sm.Any questions are welcome Best regards, Andrey Ivashov. 2 users thanked Andrey Ivashov for this useful post. on 01/06/2012(UTC),  on 01/06/2012(UTC)

I have to say that using those variables might be quite useful, but sometimes a bit confusing.Regarding your example, and by playing a bit, I could see that the region will be "someVar=0" when you open the file. When you repeat Recalculate page, someVar will have values 1,2,3,4.....which is expected to be. On the other hand if you move that region above and below if clause subsequently, then the values will have step two, actually you will get 21,23,25...I've also noted that with the simple example1: a:=12: a:=a+13: a=24: a:=6Now, if you move 4: below 1: you will get ("a" will be 7 as expected)1: a:=14: a:=62: a:=a+13: a=7When you just move it back, then "a" becomes 8?If you continue moving 4: below 1: and back, value of "a" will get values 7 and 8 subsequently1: a:=12: a:=a+13: a=84: a:=6When you recalculate page at this time, "a" will become 2, as expected.Is there something I do not understand here?. I think that this moving the definition of an absolute variable above and below the region when that variable changes the value is a bit problematic at the moment. I think that variable should not change the value when we get it back. Aactualy, I think that variable "a" should retain the value 7 and not change to 8.Regards,RadovanEdited by user 01 June 2012 12:19:16(UTC)  | Reason: Not specified When Sisyphus climbed to the top of a hill, they said: "Wrong boulder!" 1 user thanked omorr for this useful post. on 01/06/2012(UTC)

So when you move a back to the bottom SMath Studio performs evaluation starting from second expression and not from the top. 1 user thanked kmihaylovich for this useful post. on 01/06/2012(UTC)

I tried to make an absolute function and then the region disappeared, and everything else disappeared. I got it back by clicking in the worksheet area. It happened to me few times before, sometimes SMath crashed, but could not reproduce it. Look at this video, please.Regions disappearRegards,Radovan When Sisyphus climbed to the top of a hill, they said: "Wrong boulder!"

I just bumped into it when tried to use absolute functions.I think this might be considered as a bug then.Regards,Radovan When Sisyphus climbed to the top of a hill, they said: "Wrong boulder!"
