Hi,

Someone sent me this codes. Is it VBA codes ?
Is it for random number generator ?

[italic][b]Public i97, j97, u(97) As Double, c As Double, cd As Double, cm As Double, uni As Double
Public Sub Init()
Dim i, ii, j, k, ij, kl, l, m, jj, ivec, i5, j5, s As Double, t As Double
ij = Seed1
kl = Seed2
i = ((ij / 177) Mod 177) + 2
j = (ij Mod 177) + 2
k = ((kl / 169) Mod 178) + 1
l = kl Mod 169
For ii= 1 To 97
s = 0#
t = 0.5
For jj = 1 To 24
m = ((i * j Mod 179) * k) Mod 179
i = j
j = k
k = m
l = (53 * l + 1) Mod 169
If ((l * m) Mod 64) >= 32 Then s = s + t
t = 0.5 * t
Next
u(ii) = s
Next
c = 362436# / 16777216#
cd = 7654321# / 16777216#
cm = 16777213# / 16777216#
i97 = 97
j97 = 33
End Sub

Public Function RND() as Double
uni = u(i97) - u(j97)
If uni < 0# Then uni = uni + 1#
u(i97) = uni
i97 = i97 - 1
If i97 = 0 Then i97 = 97
j97 = j97 - 1
If j97 = 0 Then j97 = 97
c = c - cd
If c < 0# Then c = c + cm
uni = uni - c
If (uni < 0#) Then uni = uni + 1#
RND=uni
end Function[/b][/italic]
