   2. Well, someone once told me that it was specified to be
      case insensitive but I can't remember who that was.
   3. I thought it was specified to be something too but
      most programs largely ignore specifications in my experience.
   4. Specifications are for sissies, real crystallographers
      don't depend on them.

Hi James

2 answers from me. Personal answer: 4. Practical answer: 5. And 5 is 
"Some programs do care about what's present in these columns, so I adapt 
and place there whatever is required by the program I am using".

Fred.

PS And what I find really annoying is the atom type specified in columns 
77-78, since the information is already present in the same line, as " 
CA", " N", "HG" etc. Sometimes I just forget to check what's present in 
these 2 columns and I have problems with some programs that refuse to run.
