hi,

I was just wondering how random numbers are generated ? I am using EnhBASIC to display patterns on a text screen but the patterns don't seem very random. I'm wondering if this is a problem with hardware or is it a built in feature of EnhBASIC ?

Hi Rob,

The RND() function in EhBASIC uses a 31 bit maximal length PRNG.

I chose this for two reasons - speed, and it ensures all the values
will eventually be produced.

If you want a more random seeming sequence then use every nth
value (where n is a suitable large prime number). EhBASIC68k
uses every 5th value to this end.
