Making PERSISTENT Comments in .DXF files?

[Gooserider]

I am wanting to put some comments in some .DXF files that I am creating with QCAD pro-edition. I have found in the AutoDesk documentation that one can put comments in the file using the following structure

Code: Select all

999
this is a comment
999
this is another comment


If I open a file with VIM I can edit it, and put in my comments, but if I then use QCAD to open the file, and then save it, (regardless of whether I have made any changes!) my comments are removed from the saved file

How can I make a PERSISTENT comment in a .dxf file?

Ideally I would like the comments to last through having the file saved under another name, but even if they only stay in the file when it is saved under it's own name, that would be better than nothing...

I do notice that the lines

Code: Select all

1:999
2-dxflib 2.2.0.0


DO seem to show up in the saved file every time, even if deleted in the original...

Thanks,
Gooserider

QCAD does indeed not retain any comments in a DXF file.
