Re: cgidev2 -- RPG400-L

CGIDEV2 normally uses a template file, also called externally described HTML, for sending HTML to the browser.

The code you referenced is used in the sample program STATE when the program is unable to read the externally described HTML. In this case, it uses the WrtNoSection subprocedure to build a message for the browser without using a named section (portion) of any template file(s).

WrtNoSection is able to send large quantities of data by using a pointer to the data and the data's length. In this case, the variable 'out' is varying, so its first two bytes are its length. Therefore the two parameters are %addr(out) + 2 and %len(out).

WrtSection(*fini) is a special use of WrtSection that tells the service program to write all the HTML that has been buffered to standard output.

There is no CGIDEV2 function like the one you requested. Normally, it is not needed because all the standard HTML is contained in the template file(s).

I recommend that you spend some time with the CGIDEV2 tutorials at IBM's Easy400 site: http://www-922.ibm.com/cgidev2o/tutorial.htm.

Also, you might want to join the Yahoo Easy400Group at http://groups.yahoo.com/group/Easy400Group/. This group's purpose is thus:

This might be a web400 question... since it's rpg, I wasn't sure...
I found this section, of code, if I wanted to write html straight to the
browser without using the substitute functions.  I was wondring if there was
a better routine?
c eval out = 'Content-type: text/html' + c newline + newline + '<html><body><head> - c <title>State Demonstration</title></head> - c <body title="State"><h1 align="center"> - c State Demonstration - c </h1><p>Error(s) ocurred. Programmer has - c been notified. Please try again later. - c </p></body></html>' c callp WrtNoSection(%addr(out)+2: c %len(out)) c callp WrtSection('*fini')
I would like a routine that does a simple out &  does the *fini... ie:
c                   callp     wrtweb('<td>name</td>')
Is there a function that does this? Or would I need to write a procedure to
combine the above functions?  Also, in the previous section, why would they
offset the %addr(out) by +2 (it was like this in the sample programs??)
Thanks, for your time, tim
