User-defined HTML3 classes

The HTML3, Frameset and Frame classes can be customized in subclasses by declaring a new HTML3 class in a package DLL:

CLASS MyHTML3 FROM HTML3 
   <...> 
ENDCLASS

The WAA is instructed to instantiate a user-defined HTML3 class with a hidden input variable included in a HTML form definition, for example:

<FORM ACTION="/cgi-bin/waa1gate.exe" METHOD=post> 
<INPUT TYPE=hidden NAME="WAA_PACKAGE" VALUE="MyDll"> 
<INPUT TYPE=hidden NAME="WAA_FORM"    VALUE="MyFunc"> 
<INPUT TYPE=hidden NAME="WAA_HTML3CLASS" VALUE="MyHtml3">
<INPUT TYPE=submit VALUE="Send it"> 
</FORM>

This way it becomes possible to use HTML classes specialized for a particular HTML form-definition.
