My project is to take an input file and reverse the text, but first I want to concentrate on just plain reversing a string.

This program has no errors, but it doesn't display the reverse string


source BYTE "This is the source string",0
target BYTE SIZEOF source DUP('#')

main PROC

	mov esi, 0
	mov ecx,SIZEOF source-1
	mov al,source[esi]
	mov target[esi],al
	inc esi
	loop L1
	mov esi,OFFSET target
	mov ebx,1
	mov ecx,SIZEOF target
	call DumpMem
main ENDP
END main

An easy way would be to push each character onto the stack, and then create a loop to pop and print each character. The characters will come off in reverse order from the stack.
