Re:   SAP41

A message on TCBBS stated that SAP41 wrecked disks!  I had to try it,
Sure did!  Compare SAP41 to SAP40 and in the "CLNLOP" routine of SAP41
there is a jump:

     JC    FIL$E5

in SAP40 it is:

     JZ    FIL$E5

This would replace each valid directory with "E5"s.

You know, guys,

that's a REALLY elegant bug - a mere JZ changing each valid directory
entry to E5!  I've never done that well with MY bugs!  Usually at least
a half dozen different incorrect instructions to just trash part of
my hard disk!  My congrats.
