thx tobot my problemo of the moment is:

can u say "and" in ML?  like I want 2 do a twin prime tester and I want to say:

fun twinprime 0 = false
| twinprime 1 = false
| twinprime x =
if prime x = true AND prime (x+2) = true
then true
else false;

yea nevermind my other annoyance questions sry!!!!!

i am the win again:

twinprime (test whether x is a lower twin prime)

fun twinprime 0 = false
| twinprime 1 = false
| twinprime x =
if (prime x) andalso (prime (x+2))
then true
else false

TWINPRIMELIST (a list of twin primes <= x)

fun twinprimelist 0 = []
| twinprimelist x =
if twinprime x
then x :: x+2 :: (twinprimelist (x-1))
else (twinprimelist (x-1));


now i will get my lazy counterpartners 2 make the "perfect number" (i.e. number whose factors added up = the number like 6 (1+2+3=6 and 1*2*3=6) list program!!
