Dynamic Creation of Array

3 posts in this topic

Dear All,

I have to create a array with names such as:

Value1[2] ;

Value2[2]

Value3[2]

.

.

.

Value50[2]

where

Value1[0] = "1".

Value2[1] = "Boolean1".

The same thing follows for other 50 Value array's

I have attached a snippet of code for reference. Please review it and help me.

for $i = 1 to 50 STEP 1 ; Making 50 points
    
    $arrayname = "value" & $i
    
    $arrayname[0] = $i
    
        $str1 = ' " '
        $str2 = 'Boolean'
        $cstr = $i
        $str3 = ' " '
        $namestr =  $str1 & $str2 & $cstr & $str3
    $arrayname[1] = $namestr
    
Next

The above code throws a error "Subscript used with non-Array variable."

Can anybody please suggest how to move on with it. How to create arrays Value1, Value2, ..... Value50

and this inturn takes values as

Value1[0]

Value1[1]

If I understand correctly ou need 50 (fifty) two-dimensional arrays?

Easiest way I can think of is a 3-dimensional array.

1st dimension = rows

2nd dimension = columns

3rd dimension = arrays

Global $array[50][2][50]
 
$array[2][0][5] = 50

Sets the 3rd row, first column in the 6th array to value 50 (because all index values start with 0).

Fill all cells with "0":

; Fill in a loop
For $iArray = 0 To UBound($array,3)-1   ; Loop through all the arrays (dimension 3)
    For $iColumn = 0 To UBound($array,2)-1  ; Loop through all the columns (dimension 2)
        For $iRow = 0 To UBound($array,1)-1     ; Loop through all the rows (dimnsion 1)
            $array[$iRow][$iColumn][$iArray] = 0
        Next
    Next
Next

anks,

Why not use a single 2D array like this - much easier to code and probably much easier to address eslewhere in your code!: :blink:

#include <Array.au3>

Global $aValue[51][2]

For $i = 0 To 50

    $aValue[$i][0] = $i
    $aValue[$i][1] = '"Boolean' & $i & '"'

Next

_ArrayDisplay($aValue)

As usual, ask if anything is unclear. ;)
