Create A Program (CGI)

The main part of CGI program is implemented as an FML::CGI::XXX class. These modules have the following relation.

        FML::Process::Kernel
                |
                A
        FML::Process::CGI::Kernel   uses-a CGI
                |
                A
        FML::Process::CGI
                |
                A
        FML::CGI::XXX

How to write CGI programs is same as one of CUI. GUI modules locate under FML::CGI to clarify the difference between CUI and GUI.

In the case of CGI, prepare the following methods for screen control in FML::CGI::MODULE.

html_start()
html_end()

and

run_cgi_main()
run_cgi_title()
run_cgi_navigator()
run_cgi_menu()
run_cgi_command_help()
run_cgi_options()

These methods are called from verify_request() and run() in FML::Process::CGI.

CGI process is driven by FML::Process::CGI. run() method calls

$curproc->html_start($args);

call a set of run_cgi_xxx() methods

$curproc->html_end($args);

to control screen.

At 2001/11, FML::Process::CGI::Kernel consists of the following methods: [1]

new()
prepare()
verify_request()
run()
finish()

You do not need edit these files. FML::CGI:: is called at run() method.
