Have you looked at the web site http://bio.perl.org? To see the FAQ,
go to FAQ - (it is a little light- if your question is not answered,

bioperl.pod which gives you an overview.
If/when you donwload the distribution, look in the example directory
to get an idea about how to use the modules.

To be honest, I don't think you will have much luck in bioperl, though
the ability for the sequence object to truncate from xxx to yyy might be
Where are you getting the information about the start point? (from the
embl feature table?).
Good luck. If you want any more help, do just email again.
