; this is an example of how to make a ".bin" file. 

name "bintest"

; directive to create bin file: 
#make_bin#

; where to load? 
#load_segment=1234#
#load_offset=0000#

; set these values to registers on load: 
#al=12#
#ah=34#
#bh=56#
#bl=78#
#ch=9a#
#cl=bc#
#dh=de#
#dl=f0#
#ds=ddee#
#es=abcd#
#si=aaaa#
#di=cccc#
#bp=dddd#
#cs=1234#
#ip=0000#
#ss=3000#
#sp=ffff#

; when loading "bintest.bin" file in emulator 
; it will look for a "bintest.binf" file, 
; and load ".bin" file to location specified 
; in that file, registers are also set using 
; information in that file (open this file 
; in a text editor to edit or investigate). 
; 
; ".binf" file is created automatically 
; by compiler when it processes the above 
; directives. 



; this sample just prints out a part of 
; some ascii character set, in an eternal 
; loop, press [stop] or esc to terminate. 


start:

mov     al, '0'
mov     ah, 0eh

print_more:

int     10h
inc     al

; keep original ax: 
mov     cx, ax

;============================ 
; check for esc key to 
;    reboot: 

; check for keystroke in 
; keyboard buffer: 
mov     ah, 1
int     16h
jz      key_processed

; get keystroke from keyboard: 
; (remove from the buffer) 
mov     ah, 0
int     16h

; press 'esc' to exit: 
cmp     al, 27
jnz     key_processed
hlt

key_processed:
;============================ 

; restore original ax: 
mov     ax, cx


cmp     al, 'z'
jbe     print_more

mov     al, '0'
jmp     print_more
