There’s not a lot of information on the web
available for RSP from Prodata Systems, so this page will include things I’ve found
during my RSP development. Thanks to Prodata's Support staff
for some of these items.
All development was done using the WDSC IDE.
Coding Tips
Posting back to the same page - If you want
to redisplay the same RSP page when a user clicks on a submit
button, instead of coding the RSP Page name in the Form Action, use
the following syntax to retrieve the name of the current page.
That way if you rename your page, the code will still work
<form name="form1" method="post" action=<%= %Trim(RspGetInfo('REQUEST_URI'))
%>>
This will return something like -- "/currentPagename.rsp"
Compile Errors
Generating a Compile listing - When compiling through the RSP Editor,
sometimes compile errors are not very self-explanatory. From the
WDSC menu, under Window-Preferences choose "RSP Setup". Change the
"Print Compile Listing" to *YES. The compile listing will be in
your WRKSPLF on the iSeries.
Field Not defined errors –
If you receive a compile error that a field is not defined, but you
have defined it, try this – Right click in the source member and
select "Cleanup Document" - Check the box "Convert line delimiters
to" and select "Windows" then press OK. Recompile your file.
File Not Found errors/Library List issues
-
Tied to the RSP instance
configuration is a JOBD. You can see this by right clicking on the
instance in the editor and selecting "Configure". The JOBD is used
for a library list. We do not look at any other aspect of the JOBD.
This is the library list used for both compile and at run time.
Binding errors - Compiles are actually
executed by a job named QZDASOINIT on the System i, so for any
errors telling you to check the joblog, you should check the joblog
for the QZDASOINIT job.
Compiler cannot determine how program can end
- Unless there was a blank script tag after the *INLR line at the
end of the main code processing I received an error that the
Compiler could not determine how the program can end. Once I
put in the highlighted lines below, it compiled correctly.
%> </body> </html> <% C Eval *Inlr = *On %> <% P*-------------------------------------------------- P* Procedure name: FirstProc
Source not all included in compile - I ran
into a problem where the source in my compile listing did not
include all of the source from my source file. It was
because I was missing an ending tag "%>". All RPG source
must be surrounded by <% and %> tags.
Syntax Embedded SQL – this is supported and should be
coded exactly like you would an SQL RPGLE program. The extension of
the file should remain RSP.
Javascript –
This is supported and
should be coded just like you would in a normal HTML file. See the
sample below -
<head> <title><%= %Trim(RspSrvVar('WebTitle')) %></title><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <link href="styledemo.css" rel="stylesheet" type="text/css"> <script language="JavaScript"> <!-- function opnWindow(source, h, w) { window.open(source, "win", "height=" + h +",width=" + w + ", status=yes,menubar=no,location=no,resizable=yes,titlebar=yes, scrollbars=yes,top=" + (screen.height/2-(h/2)) + ",left=" + (screen.width/2-(w/2))); } //--> </script> </head> <body bgcolor="#ffffff" text="#000000"> <table>
