System.Random(Integer) Method

Version: Available or changed with runtime version 1.0.

Returns a pseudo-random number.

Syntax

Number :=   System.Random(MaxNumber: Integer)

Note

This method can be invoked without specifying the data type name.

Parameters

MaxNumber
 Type: Integer
The largest acceptable number. In effect, you are setting a range from one (1) to the number that you specify with the MaxNumber parameter.

Return Value

Number
 Type: Integer

Remarks

If MaxNumber is negative it acts as a positive.

If MaxNumber is zero, this method always returns 1.

A number is always chosen from the same set of numbers. Use Randomize Method) to generate a new set of numbers.

Example

This example shows how to generate a pseudo-random number. The value of the variable Number2 is positive though the value of MaxNumber is negative and the value of the variable Number3 is always 1 because MaxNumber is 0.

var
    x: Integer;
    y: Integer;
    z: Integer;
    Number1: Integer;
    Number2: Integer;
    Number3: Integer;
    Text000: Label 'Number1 = %1, Number2 = %2, Number3 = %3';
begin
    x := 100; // x is assigned a positive value.  
    y := -100; // y is assigned a negative value.  
    z := 0; // z is assigned zero.  
    Number1 := Random(x);  
    Number2 := Random(y);  
    Number3 := Random(z);  
    Message(Text000, Number1, Number2, Number3);  
end;
