4.5. ON YOUR OWN! 55

anda #$0F

; in C, use: getchar() & 0X0F

Use the above sequence to let the user specify the count. When expecting

the user to enter a value, it is a good idea to prompt the user. Your code

may look something like:...

;; various equates and comments...

;

org $2000

ldx #prompt

jsr outstrg

jsr inchar

anda #$ff

staa count

;

; rest of the code goes here

org $3000

; various RMB

count RMB 1

v RMB 1

total RMB 1

prompt fcc /How many times please? /

fcb 4

6. Write a program that will do the following:

(a) Get a number between 0 and 9 from the user and store in a variable

called v1.

(b) Multiply v1 by 4 and store the result in a variable called v2.

(d) Multiply v3 by 2 and store the result in a variable called v4.

(e) Print the values in the variables separated by a comma. In the last

lab, you saw an example for printing a colon. You can use the same

approach.

1 2 ... 50 51 52 53 54 55 56 57 58 59 60 ... 100 101
