save_levels[/qualifiers]
Save current color levels in a user specified file. The default extension of the file is .tab, and the file is written in the current directory. It might be used later to display images with the XIMAGE command DISPLAY/LEVEL_FROM_FILE/FILE=filename
Define the filename into which write the levels to save. There is no default. If the filename is not given, the user is prompted for it.
Examples:
save_levels/file=test ! save last used colour levels to file test.tab
