SHOWSTAT() (BOOLEAN)

 Function
  Determine if data is being shown on the display.

 Syntax
  SHOWSTAT()   No arguments are required

 Return Type & Value
  BOOLEAN
  Returns TRUE if data is being shown on the display, FALSE otherwise.

 Remarks
  This function allows your PPL application to determine the status of
  writing information to the local and remote displays.  Used in
  conjunction with the OPENCAP, CLOSECAP, SHOWON, and SHOWOFF statements
  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
