Hi all, I found other 49G/49G+/50G bug:

I have the array:

MTR =
[[ 1 2 3 ]
[ 4 5 6 ]
[ 7 8 9 ]]

I need to solve: 'SIGMA(m=1,3,SIGMA(n=m,3,MTR(m,n)))'

49G/49G+/50G Retunrs: 'MTR(m,1.)+(MTR(m,2.)+MTR(m,3.))+(MTR(m,
2.)+MTR(m,3.))+MTR(m,3.)'

the 48G/GX returns: 26 = (1+2+3)+(5+6)+(9)

Try it!


Note: SIGMA = SIGMA SYMBOL

Hi all,

Hi John H Meyers you are right, the SIGMA bug was found two years ago.

I am re-writting a User-RPL manual and I will have to change my
example about the double SIGMA funtion, for now.
