RE: Summation on HP 42S
Neat stuff. For something a little more complex such as summation 1 through 100 of x^2 - 3*x,

I used the idea from post 2

LBL "SUM"
0
LBL 00
RCL "T"
X^2
STO+ "X"
RCL "T"
3
*
STO- "X"
RCL "T"
DSE "T"
GTO 00
RCL "X"
.END.

Store 100 in "T", 0 in "X", Produces 323,200 in ~25 seconds
