| Name | Procedure Type | Description |
|---|---|---|
| RAN | Intrinsic function | result = RAN(i). Returns the next number from a sequence of pseudorandom numbers of uniform distribution over the range 0 to 1. |
| RANDOM | Run-time Subroutine | CALL RANDOM(ranval). Returns a pseudorandom real value greater than or equal to zero and less than one. |
| RANDOM_NUMBER | Intrinsic Subroutine | CALL RANDOM_NUMBER(harvest). Returns a pseudorandom real value greater than or equal to zero and less than one. |
| RANDOM_SEED | Intrinsic Subroutine | CALL RANDOM_SEED([size] [, put] [, get]). Changes the starting point of RANDOM_NUMBER; takes one or no arguments. |
| RANDU | Intrinsic Subroutine | CALL RANDU(i1, i2, x). Computes a pseudorandom number as a single-precision value. |
| SEED | Run-time Subroutine | CALL SEED(seedval). Changes the starting point of RANDOM. |
