  Hi Paul,  
    
  Other than sqpack and hptutil, I've not found a utility on Linux that scans  
  and repairs JAM message bases.  In the past I've moved those files to a  
  Windows machine and used FastEcho's "feutil pack -renumber" which seemed to  
  do the trick for me, your mileage may vary.  
    
  I haven't tried, but another thing you could do is use MK Message Utilities:  
    
  https://flisterz.throwbackbbs.com/filelist/BBS_Utilities/mkmu103.zip  
    
  To convert that base from JAM to Squish and then back to JAM again.
