hello everybody,
Hello,
what may cause perl to give the following command line output
Global symbol "$form" requires explicit package name at /.../Address.pm line
44.
even if the variable $form is declared in line 16 as follows
my $form = $self->formbuilder;
within a sub of a class definition.
Lexical variables (declared with my) are only visible from the point of
declaration forward within the current block/file so if you try to use
that variable before it is declared or outside the block/file in which
it is declared you will get that message.
