Hi Philip,
Thank you very much for help. Your explaination is very clear. Since I am used to
program in C++, I am quite confused about the usage of perl's variables and objects,
especially their declaration and convention. Would you give me some advice, please?
Also, I heard that using HTML::Template we could define a variable and a counter in
the template. Could you tell me how to use such features, please? I am using
HTML::Template version 2.5 . Thanks a lot.
Yours,
cwt
