Complex multi-dimensioned flexible array reallocation

[Jephir]

When I try to run this code in Turing I get an error.

Turing:

var stream : int     var _index : flexible array 1 .. 0, 1 .. 1 of string     procedure FileOpen (fileName : string)         open : stream, "data/" + fileName, get     end FileOpen     procedure FileClose         close : stream     end FileClose     procedure FileIndex (fileName : string)         new _index, upper (_index, 1) + 1, 1 %Increase dimension 1         _index (upper (_index, 1), 1) := fileName %Name dimension 1 the file name         FileOpen (fileName) %Open the text file         loop %Get all the words in the text file             exit when eof (stream) %Exit when there are no more words             new _index, upper (_index, 1), upper (_index, 2) + 1 %Increase dimension 2 to fit new word - Error occures here             get : stream, _index (upper (_index, 1), upper (_index, 2)) %Get the new word         end loop         FileClose %Close the text file     end FileIndex

Here is the error I get:

code:

Complex multi-dimensioned flexible array reallocation not implemented yet - sorry.

Anybody know a way around this problem?

Well... there really isn't unfortunately, however, take a look at the arrays tutorial in the Turing Walkthrough, as there is a really rough sort of implementation (although it's hardly a substitute.)

the real question should is why are you doing such a thing, what type of data structure are you trying to make ?

If you could explain what you are trying to read in There may be an easier way without doing multiple dimensions.

There is a way around it. But you need to know to upper limits for all the dimensions. Using this you can organize a single dimensional array so it can store you multidimensional information and access the information easily. It will take a bit of thinking. Look at my MapEditor example in my 2d tile tutorial. That method only supports 2d arrays, but adding more isn't that hard.

Alternatively you can't use a multidimensional linked list, but that's really complex

hey i tired the same thing in another program im using and if you get rid of the +1 at the end of this line

code:

new _index, upper (_index, 1), upper (_index, 2) + 1

it'll work fine... however im not too sure if it'll work in your program you'll have to test it out

Edited by Clayton: Merged the double post.
sorry for the double post but with more experiment i discovered that the code you used is whats causing problems try using this instead

code:

new arrayName,newUpper1,newUpper2

[Clayton]

In your first example, you won't ever be changing the size of your array. "Why?", you ask? Because you are just specifying new bounds for the array to be the same size that it already has by using itself as the array to reference for it's own bounds.

In your second example, what are the values of newUpper1 and newUpper2? These kinds of things make a big difference on whether the program will run or not.

ya sorry but when i ran the first i didn't realize however the second will work but note it only ran for me when i used actually numnbers and varibles can not be used I have no idea why not
