; This module same as original crt0.asm, but cut:
|
||||||
|
; 1. virtual header block (hparams change to __app_params, hpath change to __app_path)
|
||||||
|
; 2. init heap of memory - not needed because 68.18 (68.19) init heap implicitly
|
||||||
|
; (it is does dll.obj)
|
||||||
|
; 3. loader (he lives in dll.obj)
