This is exactly as it should be. To call an sub in another file via Execute
you have to provide the filename, e.g.
Execute ('bar.html#foo') ;
but the file must be already loaded before, to make sure it is, do a
Execute (inputfile => 'bar.html', import => 0) ;
before. (This import => 0 isn't neccessary anymore in Embperl 2.0)
import => 1 only works for import the sub's in the Perl namespace of the
current document. import => 0 only loads the file into memory, compiles it,
but doesn't do any import.

Yes, that's what import does.

This maybe because of the imports. From where do you call these subroutines.

you doing any imports ?

Yes, because that's not a subroutine call. Perl will stringify the xxxx, so
it executes [- 'xxxx' -] , which does of course nothing and isn't an error.
To call an unknows subroutine you must write [- &xxxx -] or [- xxxx() -]

Yes, because this does a subroutine call
