Recital Web Getting Started

Overview

Recital Web is a data centric HTTP Server that incorporates a Database and 4GL. Using Recital Web you can generate dynamic content web pages with the Recital/4GL. Recital Web can coexist with the existing Web Server on your system, so there is no disruption to your existing web site infrastructure. Using Recital Web, you can generate rich reports that can be integrated in with Recital Mirage .NET applications or Recital Terminal applications.

RSP Basics

The Recital Web HTTP server handles the generation of dynamic content HTML and sends this back to the browser that requested the page. These pages have a ".rsp" extension (Recital Server Page). Recital Firecat can serve static html pages, images, and Recital Server Pages (.rsp pages) similar to the way PHP dynamic pages are generated. With Recital Firecat .rsp pages, you can embed Recital/4GL scripting commands inside HTML documents. Recital Server Pages are really just HTML files with Recital/4GL scripting embedded within them. Any scripting commands that are embedded within the file are executed then removed from the results. All scripting code is hidden from the user viewing your web pages.

Tags

To distinguish the RSP code from the regular HTML inside the .rsp file, RSP code is placed between <% and %> tags. The tag combination notifies the Firecat HTTP Server that the code within the <% and %> should be executed by the server and removed from the results. Any output generated by the Recital/4GL code (e.g. using the ? command) will be written to the HTML output that is sent back to the web browser that requested the page.

The following example generates an HTML table that lists all the records in the Suppliers table.

<table>
<%
    set sql to vfp
    open database southwind
    use suppliers
    scan
        ? "<tr>"
        for f=1 to fldcount()
            ? "<td>"
            ? &(field(f))
            ? "</td>"
        next
      ? "</tr>"
    endscan
    use
    close databases
%>
</table>
