* This program hides any ABAP's source code and protects it with a
* password in this source code.
*
* After hiding, you can still run the abap (the load version is intact)
* but it cannot be displayed, edited, traced, transported or generated.
*
* If the ABAP is not hidden, the program hides it, if it is hidden, it
* unhide it.
* Remember to hide this program first!
