Summation on HP 42S
I tried doing a simple summation of "x" from 1 to 100. I got it to work, and correctly come up with an answer of 5050. There must be a simpler way than the contorted way that I did.

Here's my program:

LBL "SUM"
1.1
STO "T"
0
ENTER
LBL "COUNT"
RCL "X"
ENTER
1
+
STO "X"
+
+
ISG "T"
GTO "COUNT"
.END.

I begin by storing 0 into "X".

What is a better way to accomplish this?
