You have changed your requirement for what you are trying to do. You originally stated: > For example, I have a perl file that first load a huge data file then > do some processing on the data file.

For debugging an existing program as you described there, the perl debugger is one of the best choices, and you do not need to declare new lexical variables from the debugger to do so. Your latest assertion sounds like you want to do something completely different, namely to enter and run Perl code in a read-evaluate-print loop. In which case, see this article: http://chainsawblues.vox.com/library/post/a-perl-read-excute-print-loop- repl.html -- Peter Scott http://www.perlmedic.com/ http://www.perldebugged.com/ http://www.informit.com/store/product.aspx?isbn=0137001274 -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
