HP 39gii & Prime: Problems with Sequence App

Yes, that works.

But if I append +U1(N-1)*U1(N-2)*0 to an expression previously without U(N-1 or 2) the numerical evaluation takes ages.

I have found other bugs/features that render the App useless, even in comparison with the 38g.

I could never believe how bad the 38G was, I always thought "Give it a try, you missed something" - but I hadn't, it really was awful.

The only use I have for the 38G is the Sequence App, which is slow, eats up memory, poorly legible...but not buggy.

A decline to the 39gii.

Try this on the 39gii:

HP38AscD 22 N² THEN LEAST UNLISTEDRUN SEQSET:
RECURSE(U,IFTE(N MOD 2,((N+1)/2)\178,U3(N/2)),1,2)\|>U1(N):
CHECK 1:
RECURSE(U,U6(N)*(1+U6(N)*(3+2*U6(N)))/6+U4(FLOOR(N/2)),1,3)\|>U2(N):
CHECK 2:
RECURSE(U,N+ROUND(\v/N,0),2,3)\|>U3(N):
RECURSE(U,U3(N)*(U3(N)+1)/2-U5(N)*(U5(N)+1)*(U5(N)+.5)/3,2,5)\|>U4(N):
RECURSE(U,FLOOR(\v/U3(N)),1,1)\|>U5(N):
RECURSE(U,CEILING(N/2),0,0)\|>U6(N):

ie Enter the expressions manually in the Sequence App & see how the machine stymies any attempt at evaluation.

Maybe it's just my buggy software version: it's 30/Oct/2013 19148.

Anyone know of a less buggy version?
