Upper value on numerical Sigma still not fixed?
I was under the impression that the upper value limit of 1000 for numerical Sigma was removed
in the latest firmware update (I have version 5447 11252013), but when I evaluate sum(x, x, 1, 1001) (CAS mode), I still get the invalid dimension error. Works fine for upper value of 1000 or less. The firmware update list states that this problem was fixed. Is there something I am doing wrong here?

Nearly one week has gone since the question above  nobody out there with an answer?

The bug does not appear when using the template for a sum. So it looks like they fixed parts, but did not get all the cases.

There are differences between the real Prime and the emulator even if they have the same version (5447). In CAS : On the Emulator: choose sigma from the templates ==> ∑() then ∑(x,x,1,1001) [ENTER] ==> 501501 On the Prime : choose sigma from the templates ==> Sigma template to fill out, then x 1 x 1001 [ENTER] ==> "∑(x,x,1,1001) Error: Invalid dimension" Miguel

Hi John,
As HAN pointed out it's a CAS problem in the Prime. Sigma or sum works in all it's forms only in HOME mode on the Prime. Guess we will have to wait a bit longer for a complete fix. Jim
