; This file contains:
; Macros to support Object Assembler
; The InitObjects macro
; A template for TObject, the suggested root class for all objects
;
; The usable Macros in this file are documented in both the Assembler
; and MacApp manuals. Those macros are:
;
; ObjectDef
; ObjectIntf
; ObjectWith
; EndObjectWith
; ProcMethOf
; FuncMethOf
; EndMethod
; MethCall
; Inherited
; MoveSelf
; NewObject
; InitObjects
;
;
; Current limitations:
; 250 classes
; unlimited methods
;
; Object assembler programmers who do not use a Pascal main program
; MUST call the InitObjects macro at the beginning of their program.
