Linear congruential generator problem

Hi. Not sure if I am posting in the right place.

I need to make a random numbers generator and have some problems with setting some initial values. Hope someone can help me out.

I am thinking I can use the following generator which I found at: Linear congruential generator - Wikipedia, the free encyclopedia

---------- Copied from wikipedia:

http://upload.wikimedia.org/math/5/6...89fc17a049.png where *X**n* is the sequence of pseudorandom values, and

http://upload.wikimedia.org/math/d/6...756a4869df.png the "modulus"

http://upload.wikimedia.org/math/0/6...cf32d4e193.png the "multiplier"

http://upload.wikimedia.org/math/9/8...ecd37d4f6b.png the "increment" (the special case of *c* = 0 corresponds to Park–Miller RNG)

http://upload.wikimedia.org/math/3/5...9f4e1e01e6.png the "seed" or "start value" are integer constants that specify the generator.

The period of a general LCG is at most *m*, and for some choices of *a* much less than that. The LCG will have a full period if and only if:

1. http://upload.wikimedia.org/math/8/d...213956f8d3.png and http://upload.wikimedia.org/math/c/4...c0d351fe41.png are relatively prime,

2. http://upload.wikimedia.org/math/b/e...f9ef3d78f0.png is divisible by all prime factors of http://upload.wikimedia.org/math/c/4...c0d351fe41.png,

3. http://upload.wikimedia.org/math/b/e...f9ef3d78f0.png is a multiple of 4 if http://upload.wikimedia.org/math/c/4...c0d351fe41.png is a multiple of 4__.__

------------ Copy end

In my generator the m is set to 999999999 (it can also be a lower number but preferable as close to 999999999 as possible)

X0 and n will be given and be different each time the generator runs.

So what I need help with is to set m, a and c according to the rules above. Remember m should not be altered or if it must be altered then as little as possible downwards.

Hope someone can help me (Bow)
