; *  Macro Name:
; *      BEGIN_DATA( OrgAddress )
; *
; *  Purpose:
; *     This macro defines the origin in the code segment that the
; *     initialized data is to begin.
; *
; *  Preconditions:
; *
; *  Globals affected:
; *
; *  Notes:
; *     The address passed may be any valid memory address.  Note that
; *     it will be common for the programmer to use $ (current program
; *     pointer address).
; *
; *  Usage:
; *     BEGIN_DATA( ValidAddress )
; *     Where ValidAddress is a location in the Code segment where the
; *     image if the initialized data is to begin.
; *

; *
; *  Macro Name:
; *      DATA( VarName, Value )
; *
; *  Purpose:
; *      This macro defines storage in the code segment while also
; *      creating a symbol representing the location the data will
; *      reside in data memory after an initialization block move.
; *
; *  Preconditions:
; *      The BEGIN_DATA macro must have been used before this macro
; *      is called.
; *
; *  Globals affected:
; *      The program counter will be incremented each time this macro
; *      is called.
; *
; *  Notes:
; *      This macro is used to create "initialized" memory.  Since TASM
; *      and the DSP-93 are not segmented memory machines, this method
; *      of creating storage in the code segment and defining the symbol
; *      for use in the data segment is used.
; *      Note that the macro uses the arbitrary 060h location to begin
; *      definitions in the data segment.
; * 
; *  Usage:
; *      DATA( LabelName, DataValue )
; *        LabelName is the name of the symbol being defined
; *        DataValue is the intialized value of the memory location
; *
