Using multidimensional arrays

One-dimensional arrays are simple lists of information. Multidimensional arrays can hold related data in columns and rows such as with a spreadsheet. This recipe will show you how to create, populate, and retrieve information from a multidimensional array.

How to do it...

Perform the following steps to create and use multidimensional arrays:

1. Create a new main stack in LiveCode.

2. On the stack or card, create the following code to create a two-dimensional array and populate it with three rows of information:

   command makemyarray
     local aMyArray
     put "J" into aMyArray[1][1]
     put "Jones" into aMyArray[1][2]
     put "United States" into aMyArray[1][3]
     --
     put "R" into aMyArray[2][1]
     put "Smith" into aMyArray[2][2]
     put "United Kingdom" into aMyArray[2][3]
     --
     put "T" into aMyArray[3][1]
     put "Johnson" into aMyArray[3][2]
     put "Canada" into aMyArray[3][3]
     
   end makemyarray

3. Use the following line of code to retrieve a specific piece of information. In this case...
