1. Sum of List SUM/SUMD/SUMF

1.1. Instruction Description

The Sum of Single Word Lists (SUM) instruction calculates the sum of all values in a list and outputs it to RES. The Sum of Double Word Lists (SUMD) calculates double words, while the Sum of Floating Point Lists (SUMF) calculates floating points.

For example, SUM D10 D0 K5 calculates the sum of all values from D10 to D14 and stores it in D0.
