Program will only print the first letter of user inputted string

Question

I am trying to make a program in LC3 that asks the user to enter a string and will proceed to print it out. My program is only ably to print out the first letter from the user inputted string. For example, I typed in "Hello" and it would only print out "H". Is there a way to fix this? thanks

.orig   x3000
Lea r1, storeString

Lea r0, EnterText
puts

LOOP
getc

str r0, r1, 0
add r1, r0, -10
brz OUTSIDE

out
brnzp LOOP

OUTSIDE

Lea r0, UserEnter
puts

Lea r0, storeString
puts

Halt
EnterText .stringz "\nPlease enter a text: "
UserEnter .stringz "\nThe text you have typed is: "
storeString .BLKW 99

.end

Learn to use your debugger. You are overwriting r1 (which is your pointer) during the end of line check when in fact you should be incrementing it by 1 so it points to the place for the next character. You are lucky this doesn't just blow up.

Something like this should work better:

LOOP
getc

str r0, r1, 0
add r1, r1, 1    ; next character
add r0, r0, -10  ; just subtract in place
brz OUTSIDE

out
brnzp LOOP
