rand Generates a random number for use in Form Processor configuration files.

$output = rand(n);

$output - A variable in which the random number is placed.
n - The largest possible number you want rand to return.
NOTE:
- rand returns a floating point number (1234.567), to use rand effectively, put it in the int function, eg:
  $value = int(rand(6))+1;
  The +1 is to raise the value from 0 - 5.999 to 1 - 6, see example below for more detail.
- For random numbers, the srand function should be used to randomize the value.

Example:

#Randomize and generate some dice rolls

$Dummy_Value=srand();
$DiceRoll1=int(rand(6))+1;
$DiceRoll2=int(rand(6))+1;
