I think you need not too worry name collision unless you intended to
submit your code to the J base library.
If you intend you rerun the code in its `base' locale, a simpler way
of not using display_resume will be close the form first or just
ignore any anticipated error.
replace the line
wd DISPLAY
with
wd ::0: 'psel display;pclose'
wd DISPLAY
or just
wd ::0: DISPLAY
If you intend to run in a new instance. It needs to rename
`display_run' to `create' and add a verb `destroy' for cleanup.
Then run the program by '+/%#' conew 'rgtVisual'
(untested)
