Build seed specifying series of $RANDOM results

Note: Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $Random_Seed function is the RandomNumberGenerator class.

This function sets a %variable or IMAGE item to a value that can be used by $Random, so that the series of numbers returned by $Random is reproducible.

$Random_Seed accepts two required arguments and returns zero.

Syntax

%result = $Random_Seed(%seed, seed_value)

Syntax terms

%result A zero, which indicates success.

If any argument is invalid or omitted, the request is cancelled.

%seed A %variable or IMAGE item to be set to a random number seed. This argument must be a string of length at least 144. %seed is initialized for a series of $Random results that depends on seed_value.
seed_value A number that determines the $Random series. This argument must be greater than or equal to -1,000,000,000 and less than or equal to 1,000,000,000.

Examples

See the description of $Random for examples of the use of $Random_Seed.
