Yes - we will encourage you to make procedures and prototype them ... all done in the IFS. Now you have to include the prototype in both the service program as well as the "client" code. This is done by the ASP include syntax (which can bed used in HTML sections and CODE section) like; Relative to the server root path: <!--#include file="Filename" --> Or Form the IFS root: <!--#include file="/MyServerpath/Filename" -->
