Generates a vector of random variates from a Uniform distribution with probability \(f (X)\) defined by:

\[f (X) = \frac{1}{B - A},X=A,A+1,\dotsi,B\]
C Generate 100 values from the Uniform distribution
    INTEGER LSTATE,N
    PARAMETER (LSTATE=16,N=100)
    INTEGER I,INFO,SEED(1),STATE(LSTATE)
    INTEGER A,B
    INTEGER X(N)

C Set the seed
    SEED(1) = 1234

C Read in the distributional parameters
    READ(5,*) A,B

C Initialize the STATE vector
    CALL DRANDINITIALIZE(1,1,SEED,1,STATE,LSTATE,INFO)

C Generate N variates from the Uniform distribution
    CALL DRANDDISCRETEUNIFORM(N,A,B,STATE,X,INFO)

C Print the results
    WRITE(6,*) (X(I),I=1,N)
