You can't make the reset do nothing - it has to jump somewhere.

The closest you could get with a BASIC program would be to make it run
the program again, or force it to reboot.  You might be able to arrange
running from a particular line number with assistance from a machine
code program.  It may be possible to trigger an ONERR GOTO, but this
isn't as safe as a RUN, because the reset might have left some variables
corrupted.
