; Purpose: To illustrate how to solve an equation such as:
; f(x) = 5x + 3 for x = 0 to 9, using 8-bit Multiplication
; The calculated x in f(x) values will be placed into the X_Values array
; The calculated f(x) values will be placed into the Results array
;
ARRAY_LEN equ 10 ; Number of values to calculate (10): x = 0 to 9
FIVE equ $5 ; Need two arrays of length ARRAY_LEN
THREE equ $3
X
db $0,$1,$2,$3,$4,$5,$6,$7,$8,$9 ; - one holds x = 0 to 9
X_End
fx
db X-X_End ; - one holds f(x) results

HSC12 汇编程序 - 解决 f(x) = 5x+3，我能够将方程的结果正确地放入内存中，价格为 1030 美元。我无法将 x 数组值 0-9 放入 x_values 的内存位置。另外我如何使用 fx 数组来保存结果并将它们放在结果的内存位置？任何帮助将非常感激 ！很难找到有关此主题的资源。谢谢你。
