Fast random generator

Doesn't work for me :(

[edit] even after adjusting the line \masm32\bin\ml615\ml /c /coff "vrandrottest.asm" to fit my installation (I have ml v6.15 in the normal bin folder)[/edit]

[edit] I attached the corrected source [/edit]

Hello,
I have only take a look on the code.
The thing to verify is if two series of numbers generated with the same parameters are the same.
If they are the same , it is not random.

If you use the same seed, you'll have the same sequence of numbers. This is a pseudo-random generator.
