A  draft of  a  proposed GNU  extension to  the  Algol 68  programming
language has been published today at [1].

This new  stropping regime aims  to be more appealing  to contemporary
programmers, and also more convenient  to be used in today's computing
systems, while at the same time retaining the full expressive power of
a  stropped  language  and  being   100%  backwards  compatible  as  a
super-extension.

The stropping regime has been already  implemented in the GCC Algol 68
front-end [2]  and also in the  Emacs a68-mode [3] that  provides full
automatic indentation and syntax highlighting.

The sources of the godcc program [4] have been already transitioned to
the new regime, and the result is quite satisfactory.  Take a look!

Comments and  suggestions for  the draft are  very welcome,  and would
help to move the draft forward to  a final state.  Please send them to
algol68@gcc.gnu.org.

Salud, and happy Easter everyone!
