So I need to write a program..this is the basic outline:
Start
-Print "Enter input:"
-Accept String and store from $2000 -> then print all letters in upper case
-Count String length -> print
-Count lower case letters -> print
End
**Got to use variables letterstotal = 0 and modifiedtotal = 0.
Did you try to do it? Or do you just want us to do your homework?
I've attempted it. All I've done is this..
It's a mess and doesn't work.
START: ORG $1000 *Start of code location.
MOVEA.L #PROMPT,A1 *Pointer to start of prompt text
MOVE.B #PRTSTR,D0 *Set up print string function
MOVE.W #(OUTPUT1-PROMPT),D1 *The Prompt string lenght.
TRAP #15 *Print Prompt.
* Get Sentence
MOVE.L #5,D0 *Pointer to storage for Sentance
MOVE.B #READSTR,D0 *Set up readstring function
TRAP #15 *Get string from KB
MOVE.W D1,D2 *Save Length of input string.
* Count string
MOVE.L #1,D6 *Set character count
MOVEA.L #LETTERS,A0 *Point to start of string
NEXT cmpi.b #'a',d1
blt display
cmpi.b #'z',d1
bgt display
BEQ totalletters
COUNT SUBI.B #1,D2
BNE NEXT
* Print out put prompt
MOVEA.L #OUTPUT1,A1 *Pointer to start of prompt text
MOVE.B #PRTSTR,D0 *Set up print string function
MOVE.W #(LETTERS-OUTPUT1),D1 *The prompt string lenght.
TRAP #15 *Print Prompt.
* Print the number of words in sentence
MOVE.L D6,D1 *Move the count into the print thing.
MOVE.B #3,D0 *Set up Trap 3
TRAP #15 *Print Number of Words
STOP #$2700
CONVERT cmpi.b #'a',d1
blt display
cmpi.b #'z',d1
bgt display
subi.b #32,d1 ;convert lowercase to uppercase
add.b #1, modifiedletters
display move.b #6,d0
trap #15
bra next
modifiedletters addi.b #1, D3
jmp CONVERT
totalletters ADDI.B #1,D6 *Increace Count
JMP COUNT
PROMPT DC.B 'Enter input:'
OUTPUT1 DC.B 'Number of letters: ' *Text for out put
OUTPUT2 DC.B 'Number of lower case letters: '
LETTERS DS.B 99 *Thing to store the sentance (max 80)
PRTSTR EQU 1 *Print string function.
READSTR EQU 2 *Read string function.
END $1000I am still a n00b with assembly and this is unfamiliar syntax o.O
