RPL Debugging, Arrays
The Arrays Panel displays RPL arrays.  The HP49 also has matrices, these are not currently displayed.

On the left side of the panel is a list of all arrays currently shown in the various panels on the RPL Debugging Window.  Clicking on one of these entries will display that array's data in the control.  Each entry in the list is identified with a number, the type of data contained in the array and the dimensions of the array.

Array Identifying Numbers
The identifying numbers for the arrays are also shown in the other panels of the RPL Debugging Window.  For example in this Local Panel there are 4 arrays shown.  They are identified with the numbers 4, 5, 6, 7.  This helps to pick out the proper array in the Array Panel.

Here is a Stack Panel showing 3 arrays.
