I'm trying to write this simple program where I get NASM to input two different strings and then I output them separately, I'll be outputting the second one backwards once I get my program to work.
The problem is that after the first input, I get the message requesting the second output but then it goes straight into input. is it actually possible to input more then one value in NASM?
Here's the code:
segment .data
msg1 db 'Type-in 25 characters of text: ',0xA
ln1 equ $-msg1
msg2 db 'Type-in another 25 characters of text: ',0xA
ln2 equ $-msg2
msg3 db 'Your first inupt is: ',0xA
ln3 equ $-msg3
msg4 db 'Your second input is:'
ln4 equ $-msg4
spacer db ' ',0xA,0xA
lns equ $-spacer
segment .bss
input1 resb 25
input2 resb 25
segment .text
global _start
_start:
mov eax,4
mov ebx,1
mov ecx,msg1
mov edx,ln1
int 0x80
mov eax,4
mov ebx,1
mov ecx,spacer
mov edx,lns
int 0x80
mov eax,3 ;first input
mov ebx,0
mov ecx,input1
int 0x80
mov eax,4
mov ebx,1
mov ecx,spacer
mov edx,lns
int 0x80
mov eax,4 ;output of second message
mov ebx,1
mov ecx,msg2
mov edx,ln2
int 0x80
mov eax,4
mov ebx,1
mov ecx,spacer
mov edx,lns
int 0x80
mov eax,3 ;second input
mov ebx,0
mov ecx,input2
int 0x80
mov eax,4
mov ebx,1
mov ecx,spacer
mov edx,lns
int 0x80
final_output:
mov eax,4 ;outputting the first input
mov ebx,1
mov ecx,input1
int 0x80
mov eax,4
mov ebx,1
mov ecx,spacer
mov edx,lns
int 0x80
mov eax,4
mov ebx,1
mov ecx,input2
int 0x80
exit:
mov eax,1
int 0x80
