Im trying to make my own rube goldberg program using strings

[hellfix]

Im trying to add another buffer to a program but it only prints one character im
trying to make a monster prorgam full of all sorts of code but im starting with using
strings and arrays for my own rube goldberg program a bunch of simple task but
the program only prints once character i want to know why.

.386
.model flat,c
.stack 100h

includelib msvcrt

.data

printf proto arg:ptr byte
string byte "Abby","Fred","john","kent","Mary",0
buffer byte 20 dup(?),0
buffer2 byte 4 dup(?),0

.code
public main
main proc

        mov ecx,5
        lea esi,string
        lea edi,buffer
        cld                         ;set the direction flag to decrement
                ;ecx instead increment
while1: cmp ecx,0                   
        je endloop
   push ecx   
   mov ecx,4
   rep movsb
   mov ecx,0
   
while2:   cmp ecx,4
        je endloop2
   
        mov ebx, offset buffer
        mov edx, offset buffer2
     
        mov al,[ebx]
        mov [edx],al
       
        inc ebx
        inc edx   
endloop2:nop

   invoke printf,addr buffer2
   pop ecx
   dec ecx
   jmp while1
   
endloop:invoke printf,addr buffer
     
     ret
   

main endp
end main

i want to copy what has already been stored in one of the buffers to another buffer how can i do this in the simplest way

hellfix,

Yes you can have nested loops, but I'm not sure that you can do it with the HLL constructs.
