Description

The dup(value); return a space data filled with the given value. For example a 10 dup(0) return an array of 10 elements, all with a zero value.

Example 1

import "mod_say";

global
    array[] = 10 dup(0);

begin
    say ( sizeof(array)/sizeof(array[0]) );
end

This example prints 10 because the size of array is ten and the size of the first element is one.

Example 2

import "mod_say";

global
    int array[5] = 1 , 4 dup(0);
    int arrayPosition;
begin
    for ( arrayPosition = 0 ; arrayPosition < 5 ; arrayPosition = arrayPosition + 1 )
        say ( array[arrayPosition] );
    end
end

This example prints:

1 0 0 0 0

As it duplicates "0" four times in the array data.
