Help - using PVS


1. Is there any possibility to disable pretty-printing on the
proof(.prf) file ?
   I have to prove some lemmas, in which each of them had a long proof
   sequence (> 300 commands). Because of the preety printing, the proof
   exploded. each proof can take > 200K. 
2. Is there any primitive proof command to expand a definition without 
   simplification ?
3. In the middle of my proof, I wanted to expand a definition.
   Somehow, the command (ex: (expand "x")) took a very long time > 10
   Is it because of simplification ? Any suggestion on what should I do
   (If it's needed, I have a dump file for the lemma. The file size is
    around 1.2 M)
   fyi: My system is running on LINUX - PII 400 - 256M(RAM)
