; DESCRIPTION
; Macro load_library
; Logick of work.
; A first time we must to check system path, where I belive find a system library. System path is "/sys/lib/".
; If I cannot found my library, i must to check second way. Second way is current dirrectory.
; If we cannot load library, we must show the error message:
; "I'm sorry,the programm cannot found system library box_lib.obj."
; "The find was make on 2 ways: /sys/lib/ and current dirrectory."
;
; ebx,library_name
; esi,cur_dir_path
; edi,library_path
;---------------------------------------------------------------------
; Macro test_load_library
; A first time we must to check own path in current dirrectory the program, where I belive find a system library.
; If I cannot found my library, i must to check second way. Second way is system path a "/sys/lib/".
; If we cannot load library, we must show the error message:
; "I'm sorry,the programm cannot found system library box_lib.obj."
; "The find was make on 2 ways: /sys/lib/ and current dirrectory."
