TWO-DIMENSIONAL ARRAY SYNTAX
Richard November '98
Example 1.
(The simplest).
const
maxX = 1024;
maxY = 780;
var
pixelArray[1..maxX, 1..maxY] of Integer;
elements accessed like this:
pixelArray[x,y] := 69;
(where x and y are integers);
***********************************************************
Example 2.
type
TCoord = record
X: Integer;
Y: Integer;
end;
var
CoordArray: array[0..100] of TCoord;
elements accessed like this:
CoordArray[n].X := 0;
CoordArray[n].Y := 0;
(where n is an integer)
***********************************************************
Example 3.
This one's interesting because the array indeces are a character and an integer:
const
last_row = 'J';
last_column = 10;
type
TSeat = record
seat_number: String;
customer_name: String;
booked: Boolean;
end;
type
TSeatArray = array ['A'..last_row, 1..last_column] of TSeat;
var
SeatArray : TSeatArray;
elements accessed like this:
SeatArray[row,column].customer_name := 'John Smith';
(where row is a character in the range A to J and
column is an integer in the range 1 to 10)
