The message file contains a pointer that tells it where to write the 
next message.  Once in a while something bad happens - program or 
machine crash usually - that causes it to be set erroneously.  The best 
way is to exit aips and then delete the file.  When you start up a new 
one will be created.

The file is in your disk 1 data area and is named

   MSDuuu000.uuu;

where uuu is your user number in extended hex (base 36).  There is a 
verb in aips and a script in the aips system area called EHEX so that
    EHEX nnn
will tell the uuu for user number in decimal nnn.
