Extent of LOOP in MACL?

[Dan Cerys <cerys@BBN.COM>]

      I'm interested in the extent of the features available in the LOOP
      macro for MACL 1.3.  Is the extended loop macro available?  Is it part
      of the distributed code?  I know I've (once upon a time) seen a public
      domain version of the extended LOOP macro, has anybody had any
      experience using it under MACL?

There is a version of the LOOP macro available for FTP on ai.ai.mit.edu in
the pub/ directory.  It works unmodified under MACL.
