;
; This file contains three macros used in debugging the system. If the
; variable "itest" (in msbio.asm) is nonzero code is included in the
; modules to print debugging messages. The level of debugging is controlled
; by the value of the variable fTestBits in msbio.asm. Specific bits in
; the variable determine which messages to print. The equ's below tell
; which bits control which funcitons. For example the fifth bit
; cooresponds to disk activity (see fTestDisk equ below).
;
; The macros in the file are:
;
; message Prints an ascii string on the screen.
; Example usage:
;
; message fTestDisk, <"Start Disk Write", CR, LF>
; message fTestINIT, <"Begin BDS initialization">
;
;
; MNUM Print the value in a register or memory location on
; the screen. Value is displayed in hex.
; Usage:
; MNUM bitpattern, valueLocation
;
; valueLocation is typically a regester:
;
; mnum fTestCom, AX
; mnum fTestDisk, DX
;
; ValueLocation can also be a memory location:
;
; mnum fTestINIT, Final_Dos_Location
;
; If no valueLocation is given the macro defaults to
; the BX register.
;
; ZWAIT Stops the program until any key is pressed.
;
;
; The three macros preserve all register values. If "test" is zero
; defined during assembly then the marco produce no code.
