Hide and password-protect any ABAP's source - still runs, but can not be displayed, edited, transported or traced

Внимание! Сделайте архив защищаемой программы перед использованием!

Code:
PROGRAM ZHIDE NO STANDARD PAGE HEADING.
************************************************************************
* This program hides any ABAP's source code and protects it with a
* password. One can still run the abap (the load version is intact)
* but it can not be displayed, edited, traced, transported or generated.
* If the ABAP is not hidden, the program hides it, if it is hidden, it
* unhides it.
* The password is hard-coded in a source code, so the first candidate
* to be hided sholuld be ZHIDE itself.
************************************************************************
