Chapter 13 Arrays Part 2
what you want to fill it with-O, which is Drd(False), that is, the
numeric equivalent of False. Now you just need the length in
bytes ... which brings you to the next procedure: SizeD'. SizeD'
can take as its argument any variable or the name of any data
type.lt returns the size of that variable (or of a variable of that
type) in bytes. So, to initialize Base, you could write:
FillChar(Base,8izeOf(Base) ,0);
This statement will set all bits and bytes in Base = to o. The
combination of FiIIChar and SizeD' is a hard one to beat,
especially for array initialization.
13.3 ORDER OF ELEMENTS
The elements of an array are stored in a specific order. The order
is different for CP/M-SO systems than for all other version of
TURBO Pascal. The following description applies to all versions
of TURBO Pascal except CP/M-SO:
If the array is one-dimensional-that is, if it has only one indexthen
the elements are stored in ascending order. For example,
the array List (defined as array[O .. 9] of Integer) stores its
elements in the order List[O], List[1], List[2], and so on ... basically
what you would expect. But what about multi-dimensional
arrays? The array Stars is defined as
var
Stars : array[XRange,YRange] of O .. StarMa.x;
where SRange = 1 ... S. So, the question is, are the elements in
Stars stored as Stars[1, 1], Stars [2, 1], Stars[3, 1], etc., or are they
stored as Stars[1,1], Stars[1,2], Stars[1,3], and so on? Pascal
itself gives you the answer to that question. Remember that your
definition above is just shorthand for
array[XRange] of array[YRange] of O .. Starma.x;
