(...) Travis, I could not agree more. I've been tossing around the concepts of an LDraw file format standards body with Tim and others, and IMHO the weakest link in the LDraw file format is that comments and meta-commands use the same record type. (...) (22 years ago, 14-Mar-03, to lugnet.cad.dev)

(...) Kevin & Travis - These are very good points. As a non-programmer, but someone who has a general knowledge of the LDraw file format, I think it is a good idea to separate comments from meta-commands. Also, talk of a standards body is a good (...) (22 years ago, 14-Mar-03, to lugnet.cad.dev)

(...) Why not force comments to be a meta-command like MLcad does with WRITE? Then the only problem you have is new files created with Ledit, and old files which will need to be converted. And Ldraw would still handle them OK. ROSCO (22 years ago, 15-Mar-03, to lugnet.cad.dev)

(...) Why not keep previous meta-commands where they're at, but also introduce a new line-type exclusively for meta-commands? I'm not too keen on MLCad's WRITE, to me it makes little to no sense. Maybe if it was COMMENT or even ! (like an HTML (...) (22 years ago, 15-Mar-03, to lugnet.cad.dev)
