I'm trying this gen routines. In the manual, under urd and duserrnd opcodes
pages, it's tell that this gen don't need have size (lenght) of power of 2 ;
if I've understand, lenght it's same of size. Or not?. But i can't use a
different size. They work only with power of 2 size.
Does wrong the manual, or do I wrong somethings ? 
Thanks for any advices.

Yes, thanks.
They are really simple, cause i want to understand their behavior.

Ex_1 had table size of 1000, and tell me illegal table lenght, Ex_2 use 1024
size and go right.

Ok, wrong ex_01,
it was 





	sr     = 40000
	kr     = 100
	nchnls = 1

instr 1

k1 = urd(1)

k2 duserrnd 2

printk .25, k1
printk .25, k2

endin




f1 0 1000 -42  0 1 100	1 2 100		2 3 300		3 4 500

f2 0 1000 -41  0 100 	1 100	2 300	3 500
;
i1 0 10

I see ...
If you want to use a non-power-of-two function table, you must give a  
size with a negative value. So in your case:
f1 0 -1000 -42 0 1 100	1 2 100	 2 3 300	 3 4 500
f2 0 -1000 -41 0 100 1 100	2 300	3 500
should work. Perhaps you can test it, too.

Try:
f1 0 -1000 -42  0 1 100 1 2 100 2 3 300 3 4 500

f2 0 -1000 -41  0 100 1 100 2 300 3 500


In order to give NP2 lengths, these have to be passed as negative p3s

yes, now all is right.
Many thanks, but... why this? If it's not many complex, i would like to
understand.
Anyway now it's working, and thanks for this.

Ok, now all works well.
Many, many thanks. I've found in manual, under f statement page, this
explanation (sometimes i forget to read somethings!). I'm not able to
understand why, but important thing is that now i can study.
(Maybe it will be better if this would be write in gen/opcode pages).

thanks e ciao,

franc

That is because when reading an ordinary f-statement, csound will
check if it's power-of-two (or +1) automatically, regardless of
anything else. Making it negative disables this check. The check is
important because many opcodes depend on tables being power of
two and will be broken if they aren't.
