Hello
I have a rather complex mod_perl CGI which calls pages from
a database which are intereted with EMBPERL.
I seem to randomly loose my objects from the EMBPERL pages.
For example we have one page from the database called with the following code:
1 [- use FINANCEMOD;
2 $obj = FINANCEMOD->new(\%fdat) -]
3
4 [$ if $fdat{finance_page} eq "result" $]
5 [- $obj->init_results();
6 $obj->create_statement();
7 $html_txt = $obj->get_html_txt();
8 %fdat = %{$obj->{'_fdatref'}}; -]
9 [$ endif $] [# finance_page = result #]
10
11 [# print the top of the page #]
12 [- $head = $obj->page_head(); -]
13 [- $escmode = 0 -]
14 [+ $head +]
15 [- $escmode = 3 -]
16
17 [$ if $fdat{finance_page} eq "result" $]
18 [# pass all needed fdat and object values to local variables for use below #]
19 [$ if ($html_txt->[0]) $] [# If there are results, print the table. #]
I get the following error:

If we don't include the semicolon after the use statement, the module
fails to be called into the program at all.
What is the best way to make sure use works in a page?
I'm very confused about how the scoping works. It looks like a bug in
EMBPERL. The documentation on the scoping is also confusing
What exactly is the difference between [- -] and [* *]?
