Dear Marc, dear Forum,

See the section

?More About Global Variables

in the GAP online help.

For example:

gap> NamesUserGVars();

gives you a list of names of global variables created after loading 
the library. Or

gap> Filtered(NamesSystemGVars(), 
>              str-> IsBoundGlobal(str) and IsFunction(ValueGlobal(str)));

gives you the names of global variables bound to functions during loading 
of the library.

Currently, you can get the names of packages (normalized to lower case) found 
in the package paths with:

gap> RecFields(GAPInfo.PackagesInfo);

But this is not (yet?) documented.

With best regards,

   Frank
