The DISPLAY command controls fScan's interactive display properties.

DEV - The DEV argument can be any recognized X host; default is local display.
- Examples: myhost, myhost.biac.duke.edu, 152.3.98.222
FLG - The FLG argument is a bit flag with the following meanings:
- 1 - show only one window at a time (<enter> or 'j' to switch)
- 2 - onscreen (overrides default OFFSCREEN setting when displaying across a network)
- 4 - offscreen – render 3D graphics to buffer, then transfer to display (default for networked display)
- 010 - open all data windows initially (default is to only open if < 10 data sets)
- 020 - only display main interactive menu
- 040 - don't display any interactive menus
- 0100 - don't display window text
- 0200 - don't display any windows (for running scripts with embedded interactive commands)
- 01000 - turn windows on/off to raise to front (use if window manager does not raise windows properly)
- 02000 - flip RGB bytes when creating JPG images

PANELS - PANELS can be used to specify how many rows to use for showing images; the default is to arrange panels in multiple rows (see also '-set showpanes').
ZOOM - Zoom factor to be applied to all windows (see also '-set showzoom').
- ZOOM 0 - no zooming
- ZOOM 1 - zoom by 3/2
- ZOOM -1 - zoom by 2/3
- ZOOM > 1 - zoom by ZOOM factor
- ZOOM < -1 - zoom by 1/ZOOM factor
TNAM - TNAM is a character string to use as a filename prefix when creating TIFF files. The normal filename can be overridden when creating TIFF files interactively. The default prefix is the source file name (INFILE). (See also '-set tiffname').
NCOL - NCOL can be used to specify the number of palette colors to use (partially implemented).
HDRTXT - HDRTXT is a text string that will be displayed in each window (see also '-set showtext')
SCAL - SCAL is the initial intensity scaling factor to be applied to all windows; the default is 0.0, which results in autoscaling (see also '-set allscale')
