Hi, I´ve got a doubt about arrays.
How I can put vaiables in a bidimensional array, in one dimension I make something like this

dim myArray[5]
myArray[5].xpos=300

for 2 dimensional array, I stay frozen here

dim myArray[5][3]=300
myArray[5]???=???  ???

I don´t kwon the sintaxis for more of one dimension Array, for put in a value for every dimension.

Thanks for your time and help.

Best regards mentalthink


DIM data[100][100]

data[x][y] = z // no space between ] and [ !!


HI, kitty thanks!!!

But the trouble is what I want put a variable for x and another for y

DIM data[100][100]

data

• [y] = z // no space between ] and [ !!
  
  in your example, if I don´t stay wrong the value is put to x and y, but my doubt is what I want to put 2 values, one for x and another for y.
  
  Perhaps this can´t be done, I´m not programmer and my programming kwnledges are very little.
  Thanks Kitty, again.

array

• [y] makes a two-dimensional array, see it as a spreadsheet with lots of boxes, each box can be addressed with an X and a Y coordinate or column and row if you want.
  
  (column, row)
  (0,0) (1,0) (2,0)
  (0,1) (1,1) (2,1)
  ...
  

mentalthink,
Make sure you dont overstack your arrays.

if you declare DIM array[10]

then the bounds range is [0..1..2....8..9]

so this would overstack:

array[10]=12345

and this would be your last slot, and no overstack:

array[9]=12345

an overstack causes crash.

You can put X and Y like this:



TYPE MyArray
    x
    y
ENDTYPE

GLOBAL MyCoolArray[] AS MyArray

REDIM MyCoolArray[10][10]

MyCoolArray[1][3].x = 123
MyCoolArray[1][3].y = 321


and so on...

HI, Moru, Hemlos and Schranz0r, thanks for your explanations, it´s are very good for me, to continue growing my littles knowledges about programming..

Thanks again for your time, and answers.
