Internally, that compiler was known as BLISS-16C (C for cross-compiler). The TRANSF utility in RT-11 was eventually written in BLISS-16C (and common BLISS) so that one source pool could be maintained across the various operating systems (RT-11, RSX-11, VAX/VMS). EDT (I was the project leader for V3.10) used BLISS-16C for the builds on RSX-11M, IAS-11, and RSTS/E (RSX run-time environment) and BLISS-32 (eventually BLISS-64) for VMS. -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Johnny Billquist Sent: Monday, October 10, 2011 10:14 To: hecnet at Update.UU.SE Subject: Re: [HECnet] BLISS-16? All of RMS-11 is written in BLISS-16. Parts of the RSX kernel is written in BLISS-16, and also parts of DECnet-RSX is written in BLISS-16. Cross-compiled on VMS, and the result transferred back to the RSX system for the full build. Listings and stuff from the BLISS-16 compiles are distributed as a part of the RSX distribution.

The only place I ever saw it was in an Algol-68 compiler written at Carnegie-Mellon (the original perpetrators of Bliss). That was a different edition, though, called Bliss-11 and hosted on a PDP-10. paul -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Johnny Billquist Sent: Monday, October 10, 2011 9:58 AM To: hecnet at Update.UU.SE Subject: Re: [HECnet] BLISS-16? Hi, Steve. Looking for the cross compiler. (Like I said, BLISS-16 for VMS... :-) ). I've seen one reference for uBLISS, but I have no idea of the status of that one. Was it even usable? Why did DEC not use it internally for the Bliss stuff for PDP-11s?

BLISS-16C while hard to find may be available, the other one I have only seen (and used) once in the 80's while at DEC and don't expect it to be available anywhere. I will check to see if I have a copy of either, but it may take a while! I'm not sure what condition the tapes I have are in - it has been decades since they were last accessed. -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Johnny Billquist Sent: Sunday, October 09, 2011 22:09 To: hecnet at Update.UU.SE Subject: [HECnet] BLISS-16? Do anyone have BLISS-16 for VMS? I guess it might be bundled with BLISS-32, but I don't know. I would like to test it some, and I have a VAX box running VMS, but my distribution CDs are far away, and I don't know if I have BLISS in there, but I thought I'd start by asking here before I try to get access to CDs 2000 km away...
