; Use a macro to make code a little cleaner.
; The parameter varname is optional.
; Syntax to use macro is :
;  WANT equ expression
;  USE func [,varname]
; If the 'varname' is defined, a table declaration is created like:
;	GLOBAL	TableName:DWORD
; Then, the table entry is created:
;  If WANT is true, the table entry is created for the given function:
;	varname	DD	func
;  If WANT is not TRUE, a Not_Supported entry is put in the table:
;	varname	DD	Not_Supported
; The resulting tables look like:
;
;	GLOBAL	ExampTable:DWORD
;	ExampTable	DD	routine1
;			DD	routine2
;			DD	routine3
;			...
; Thus, each table is an array of function pointers.
