FORTRAN
subroutine blankt(nframes)
integer*4 nframes

Pascal
procedure blanktime(nframes: longint);

DESCRIPTION

The screen of the iris will normally blank (turn black) if the system receives no input events for about 15 minutes.  This is done to protect the color display.  blanktime makes it possible to change the time before the screen is blanked, or disable the screen blanking feature completely.  The argument nframes specifies the screen blanking timeout in frame times.  Since there are 67 frames per second, nframes should be 67 times the number of seconds that the system should wait before blanking the screen.  If nframes is given as 0, screen blanking is disabled.
