Article 172978 of comp.os.vms:

There is a version of our RTL/2 compiler product now available for personal
non-commercial use on any non-clustered VAX/VMS system. This is slightly
modified from my previous message on this as we have eased the licencing
restrictions to include any version of VMS rather than just the hobbyist 
version from DECUS.

The distribution comprises a Zip file containing a set of object libraries 
which are built into the compiler and associated tools, plus a set of runtime
support source libraries. No user privileges are required to build or run 
this software.

The software is available at:
    ftp.demon.co.uk/pub/digital/VMS/rtl2_for_hobby.zip

Please mail any queries about this software to:
    rtl2@natron.demon.co.uk


RTL/2 is a programming language of the same vintage as C and Pascal; it was
originally developed at ICI in the UK and can be regarded as a simpler 
descendant of the Algol family.


Included in the package are:
- Compiler, generates Macro32 source code
- Linkage Verifier, a tool used to check the consistency of inter-module data 
  definitions and procedure calls
- Macro Processor, a general purpose macro pre-processor tool
- Debug Interface, adds VMS Debug information to object files
- Runtime support libraries for VAX/VMS
- Help library
- LSE environment file
- some documentation


I will be adding further details on the language itself to the distribution 
when I get the chance (probably in a week or so). In the meantime, if the 
Help and LSE info isn't enough people can mail me for a draft copy of this
"documentation" or, if you have access to an academic library, you may be 
able to find one or more of:
