Apssman Library Use

[math7]

Hello, I came across the Appsman library when reading the information from the EQL + library of the remembered professor Wolfang Rautenberg, excellent programmer of many of the most useful programs for our HP 48G-GX-50g. But I don't quite understand how to use the Appsman library, because in the help it says that you have to configure the reserved variables APAR, APAR1, APAR2, etc; and in the examples that have the help it is not clear how I assign the value to each of those variables, for example if I want to assign the list {11 4 2} to customize the APPS application box and create the APPAR variable and then press the STO command to store this value in the variable and also leave the USR mode fixed (the user mode) as the help says, absolutely nothing happens, the APPS menu continues to come out complete with all the options as from the factory.

The application is at this link https://www.hpcalc.org/details/4593.

The reserved variable APAR does not appear in the HP 50g advanced user manual either, so I do not understand how its value is modified to make the Appsman application work.
