Most commands will suppress output if you add ">NUL" (note spelling: one
L, not two) at the end.  COPY, alas, is not one of these.

Some commands, like COPY, write their output to stderr not stdout.  For
such commands, you must redirect stderr.  The easiest way to do that is
to use the CTTY command, which works in all versions of DOS, at least
since 2.0.  However, I presume that each invocation of FSYSTEM creates a
temporary invocation of COMMAND.COM; thus you cannot call it three times
with "CTTY NUL", the desired command, and "CTTY CON".  Instead you must
write a batch file containing those three commands as three lines, and
call FSYSTEM to invoke the batch file.
