EDL Interpreter

FAB EDL Programming Language has been designed to enable writing small programs in an easy way.

The EDL programming language is similar to Basic/Pascal/Delphi programs. It offers most functions available in other programming languages with the advantage that special functions are available to make interfacing to teletext systems easier.

To be able to design and test the EDL programs easily an IDE (Integrated Development Environment) has been developed. It allows designing the EDL program within a modern editor with all functions that are normally offered by professional C++ compilers only.

EDL programs can be executed as standalone programs from command line by calling the EDL interpreter or within the FAB Teletext Network Controller FT-NC 2.5 which can execute EDL programs whenever a certain file has changed and can also schedule execution of EDL programs at certain times of day.

The EDL package offers the following features:
