types

Can I create own types??
I Would like to use a variable "xyz :array[1..40] of Integer", but it
doesn't work.

I assume you are referring to extending RAP, the run-time Pascal
environment.

- See the article below about Extending RAP.

- RAP does not support arrays. However it does support TList and
TStringList.

- You can also extend define Delphi classes that can be used in RAP.
Therefore another solution is to create a class that manages a list of
integers. And then define the required RAP RTTI class, again see the article
below.

--------------------------------------------------
Article: Extending RAP
---------------------------------------------------

There are two very simple and powerful techniques to extend the capabilities
of RAP infinitely. These are summarized below and covered in more detail in
the RAP.hlp online help. Demos and tutorials are installed to
RBuilder\Demos\RAP. The tutorial text is located in RAP.hlp.


1. RAP Pass-Through Functions

These are functions that appear in the Language tab of RAP's Code Toolbox.
These functions are written in Delphi and can be called from RAP. RAP's
pass-through function architecture enable's developers to add new built-in
functions to RAP's code toolbox.

2. Extend RAP's RTTI

RAP's Run-time Type information defines what classes and properties can be
accessed via RAP. By default the published properties of any class that is
registered with Delphi's RegisterClass procedure is recognized by RAP. In
addition many of the public properties and methods of ReportBuilder classes
are exposed.
