; NOTES
;
; This file contains the macros used to provide debug output services
; for the protected mode ISR.  Debug output services are fully
; defined in DEBUG386.ASM.
;
; MODIFICATIONS
;
; December 1, 1994   5.10A :  Initial release.
;

;
; Any routine that wants to use debug services can include this header
; file.  Unfortunately, if it gets included by DEBUG386.ASM, we are
; going to see a conflict between these EXTRN definitions and the
; PUBLIC definitions in the source module.  We avoid this conflict by
; simply defining _DEBUG32 in DEBUG386.ASM so that these guys won't get
; pulled in by that module.
;
; Note also that these externs don't get defined if ISR_DEBUG is not turned
; on.  This prevents this code from being linked in in a production release.

;
;  Macro: VIDGOTO row,col
;
;
;  ARGUMENTS
;
;   row : The row to go to on the screen.  This can be any sort
;         of identifier that will push 32 bits on the stack
;         with a "push row" instruction.
;
;   col : The column to go to on the screen. This can be any sort
;         of identifier that will push 32 bits on the stack
;         with a "push col" instruction.
;
;  DESCRIPTION
;
;  This macro is used in the protected ISR to move the cursor, or current
;  output location, to a specific location on the screen.
;
;  SIDE EFFECTS
;
;   None.
;
;  RETURNS
;
;  Nothing.

VIDGOTO macro row, col  ; Tag: Debug private
        push col
        push row
        call near ptr _VidGoto32
        add sp,8
        endm

;
;  Macro: VIDPUTS str
;
;
;  ARGUMENTS
;
;   str : A string that needs to be displayed on the screen.  Note
;         that this doesn't have to be a null terminated string.
;
;  DESCRIPTION
;
;  This macro is used in the protected ISR to display an entire string
;  on the screen.  It operates a little differently from the same
;  function in real mode.  This guy just wastefully uses an IRPC loop
;  to expand out to a single call to _VidPutc32 for every single character
;  in the string.
;
;  SIDE EFFECTS
;
;   None.
;
;  RETURNS
;
;   Nothing.

;
;  Macro: VIDPUTC char
;
;
;  ARGUMENTS
;
;   char : A single character that needs to be displayed on the screen.
;
;  DESCRIPTION
;
;  This macro is used in the protected ISR to display a single character
;  at the current cursor position on the screen.  It does this with
;  a single call to _VidPutc32.  Note that the argument can be anything
;  that pushes a 32 byte value with assembly of "push char".
;
;  SIDE EFFECTS
;
;   None.

;
;  Macro: VIDPUTBYTE data
;
;
;  ARGUMENTS
;
;   data : Any eight bit value that can be moved into al with
;          a mov al, data instruction.
;
;  DESCRIPTION
;
;  This macro is used in the protected ISR to display a single binary
;  byte in hex.  The real work is done by VidDat32, the macro just
;  takes care of setting things up to facilitate the call.

;  SIDE EFFECTS

;   None.
