VON -- Activate the Shell's -V flag.
usage:  VON


FORMAT

  VON

  VON turns on input verification. As commands are executed, or comments
  processed, they are written to the error output stream of the Shell.
  In Shell scripts, VON can be used to show the progress being made
  by the script.

  If VON is turned on in a shell script, it remains on until that
  shell script exits, or until over-ridden by a VOFF in a nested
  shell script. When a shell script exits, the state of input
  verification is returned to the state in effect just before the
  script was invoked.

  VON requires no arguments or options.
