  It is innocent.  The program is not trying to WRITE to the disk, it is 
instead trying to reload COMMAND.COM from the disk after the program 
terminates.  This is normal for large programs which ask for all the memory
available.

  To test it, boot from a floppy diskette that is write protected and run 
the program from there.  You don't get a "write protect error" when the 
program finishes so it is not writing to the disk.  Now rename COMMAND.COM
something else and run the program again.  You will get the "INVALID 
COMMAND.COM -- SYSTEM HALTED" error message.
