SHOWON

 Function
  Turn on display of information to the screen.

 Syntax
  SHOWON   No arguments are required

 Remark
  This statement allows your PPL application to turn on writing
  information to the local and remote displays.  Used in conjunction with
  SHOWSTAT(), OPENCAP, CLOSECAP, and SHOWOFF it allows you to temporarily
  turn off the display while capturing output to the screen.  This can be
  useful anytime you want to automate a feature for the user and allow
  them to download the resulting capture file instead of spending lots of
  time online.

 Examples
  BOOLEAN ss
  LET ss = SHOWSTAT()
  SHOWOFF
  OPENCAP "CAP"+STRING(PCBNODE()),ocFlag
  IF (ocFlag) THEN
   DIR "U;NS"
   CLOSECAP
   KBDSTUFF "FLAG CAP"+STRING(PCBNODE())+CHR(13)
  ENDIF
  IF (ss) THEN
   SHOWON
  ELSE
   SHOWOFF
  ENDIF
