;=================================
; here we define the functions
; from emu8086.inc

; SCAN_NUM reads a
; number from the user and stores
; it in CX register:
DEFINE_SCAN_NUM

; PRINT_STRING prints a null
; terminated string, the address
; of the string is in DS:SI 
DEFINE_PRINT_STRING

; PRINT_NUM prints a signed
; number in AX.
; (PRINT_NUM requires the declaration
; of PRINT_NUM_UNS).
; PRINT_NUM_UNS prints an unsigned
; number in AX:

DEFINE_PRINT_NUM
DEFINE_PRINT_NUM_UNS
