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.
