Hello! Is there anyone here that knows how to step in a buffer? Since I have problem with putting the whole code in this editor I try to explain my problem without the whole code. Lets say that I have a buffer declared as: Code: INBUFFER: .skip 128 And I have allready placed following in the buffer: 314+555 In order to read this I step through the buffer in the positions 0 to 6. So, in my subroutines I first read 314, put it in a new buffer, OUTBUFFER, and then I put the +sign and thereafter the program shall start to read the number 5 at position 4. But this doesn't work out for me. Here's how I try to do it. Code: getinpos: movl START_INPOS, %ecx movl %ecx, %ebx getchar: movl $INBUFFERT, %ebx START_INPOS has 4, which is correct, but someone told me that I'm overwriting ebx here. And I can understand that, but how should I do this. Now when starting to read, the subroutine starts to read at position 0 again , i e 3 and then 1 and so on..... Can anyone help me here? Anders
