In article <1990Sep12.190007@jellosub.luftfahrt.uni-stuttgart.de> you write:
  I guess there must be a way to open a file of type 'rec', 
  probably by an AEGIS system call, because that seems to be
  exactly what I-DEAS is doing. Perhaps it would be possible 
  to copy the 'unstruct' files to newly created 'rec'-files? 
  Unfortunately I'm not an AEGIS-programmer...

You can change file types with the 'obty' command.  It will not do anything
about the contents of the file, so simply changing your unstruct files to
rec probably won't work.

I don't think Apollo would recommend it, but you might try this.  First,
change the file type to unstruct, using 'obty'.  Then compress.  After you
uncompress, change the type back to rec.
