Releasing units without source code
It can be useful to release a FreePascal unit without publishing its source code: * The source code contains proprietary information. * In teaching, because you want to force students to use a unit by its interface (contract) only, and not by looking at its implementation.

REXX
REXX is a programming language originally developed by IBM and over time included in all IBM operating systems (e.g. OS/2, AIX and PC DOS). In addition to this, various IBM and non-IBM implementations have been made available for most operating systems/environments (including free implementations for Win32/Win64, Linux, Mac OS X, Solaris and many others - e.g. Regina, Open Object Rexx). This interface unit makes it possible to inter-mix code written in Pascal with REXX.

TAChart Tutorial: Multiple Panes in one Chart
This tutorial shows how to create a chart with multiple series in their own panes and with their own left axes and one common bottom axis. It was created while checking out the nice "Panes demo" which you can find in the folder components/tachart/demo/panes of your Lazarus installation. Since a second topic is included in this sample project it may be a bit difficult to catch the basic idea. So here we explain how you can do this from scratch.
