Calling a BSP page with flow logic from LAYOUT

Question

Hello all.  I am developing a BSP transaction to update HR data on SAP.  I initially developed this with one 'page with flow logic' and several 'page fragment's.  It has been suggested that I break this out into several pages with flow logic because the code in  the 'OnInputProcessing' Event Handler was getting quite complicated.  I was using the BSP directive to execute my 'page fragments'.  This was very simple to do.  What do I replace the BSP directive to call a page fragment with in order to call a page with flow logic.  I have included the code below.  I have converted the 'body.htm' 'page fragment' to a 'page with flow logic' and I am not sure of the correct way to call the page.  I do not have access to the navigation->goto_page( 'body.htm' ) at this point.  I am new to BSP and appreciate any help offered.

Hi,
uhmmm, as it was previously suggested, you should perhaps think about MVC for your development. Working with classes and methods gives you more room for a better looking code. But at this point I´m not sure where your real problem is. You mentioned first that you created one page with logic and several page fragments and then you are worried because the code in the OnInputProcessing event is getting out of control
First, you cannot insert a page in a page. You can only insert fragments in a page with <%@include file="header.htm" %>.
Second, if you don´t have idea of MVC or you don´t want to switch to MVC, then create a modules program (SE38) where you´ll enter your code as subroutines and you call these subroutines from OnInputProcessing as follows:
perform subrout1 in program XXXXXX tables YYYYY using AAAAA.
In your programm XXXXX you declare the code as:
form subrout1 in program XXXXXX tables YYYYY using AAAAA.
This can be a substitute to classes and methods.
