    lrand		- lehmer random number generator
INVOCATION
    long seed( lseed )
      long lseed;
    long lrand()
EXPLANATION
    Lrand(3) uses a prime modulus multiplicative linear
    congruential generator (PMMLCG) to generate a pseudo-
    random number in the range 1 to 2147483646 {LONG_MAX}-1.
    The generator is much more random than rand(3), especially
    in the low order bits. The formula used is:
      seed = (16807 * seed) % 2147483647
    Seed(3) sets the seed to an initial value, the default
    is 1.
RESULTS
    Lrand(3) returns the next value of seed.
    Seed(3) returns the previous value of seed.
