If you execute
{ } PVIEW
It will display PICT and place you in scrolling mode, in essence,
'taking over the keyboard'.

But if you execute
{ # 0 # 0 } PVIEW
It will display PICT and then go on, not entering the interactive
graphics environment.

If you want to, for example, display GROB 'A', wait 5 seconds,
then display GROB 'B' then wait for a keypress, the following
program will do it.  (I am typing this straight from the terminal,
so bear with me!)

\<< PICT { # 0 # 0 } A REPL
{ # 0 # 0 } PVIEW 5 WAIT PICT
{ # 0 # 0 } B REPL
DO
UNTIL KEY
END DROP \>>


Hope this helps!
