I  have just  found  a bug  in  the  1.5j LSVBITFD:  it  may, under  certain
conditions, crash  with an addressing  exception when presented with  a source
node  in lower  case (or  for  that matter,  with  a source  node whose  first
character does not lie in the 'A'..'Z'  EBCDIC range). I fix is available from
my server (both MODULE  and ASSEMBLE) if you'd like to install  it. It will be
in the next release of course.
