; 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."
;
;
;---------------------------------------------------------------------
; Macro sys_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."
;
;---------------------------------------------------------------------
; How can I use it?
;---------------------------------------------------------------------
;-Example using single load library
;-universal load library/librarys
;load_library library_name__, cur_dir_path__, library_path__, system_path__, \
;err_message_found_lib__, head_f_l__, myimport, err_message_import__, head_f_i__
;-if return code =-1 then exit, else normally work
