RND (Random Number)

The RND function is used to generate a random number.

Syntax

variable = RND

The example uses the RND function to generate two random integer values from 1 to 9. The SecsSince1990() instruction is used to generate the seed value for the Randomize() instruction.

'Declare Public Variables
Public SS1990 As Long 'Declare as public Long
Public Wild1, Wild2       'Declare variables.

'Main Program
BeginProg
  'Create Seed.
  SS1990=SecsSince1990(Status.TimeStamp(1,1),1)
  'Seed random number generator.
  Randomize(SS1990)
  Scan( 1, Sec, 1, 0 )
    Wild1 = Int( 100 * RND + 1 )  'Generate first random value.
    Wild2 = Int( 100 * RND + 1 )  'Generate second random value.
  NextScan
EndProg

Remarks

The RND function returns a single value less than 1 but greater than or equal to 0.

To produce random integers in a given range, use this formula:

INT( ( upperbound - lowerbound + 1 ) * RND + lowerbound )

Here, upperbound is the highest number in the range, and lowerbound is the lowest number in the range.
