;=================================
; here we define the functions
; from emu8086.inc
DEFINE_SCAN_NUM
; SCAN_NUM reads a
; number from the user and stores
; it in CX register.
DEFINE_PRINT_NUM
DEFINE_PRINT_NUM_UNS
; PRINT_NUM prints a signed
; number in AX.
; PRINT_NUM_UNS prints an unsigned
; number in AX (required by
; PRINT_NUM):
DEFINE_PTHIS
; PTHIS prints NULL terminated
; string defined just after
; the CALL PTHIS instruction:
