chips> chips_color_name( _chips->red )
  red
	

Here we convert the value _chips->red to the string "red". Since we have ignored the return value, ChIPS prints it out to the screen (see the 'Using ChIPS and Sherpa as a calculator' section of "ahelp tips").

  chips> variable colname = chips_color_name( chips.curvecolor );
  chips> print("The color of curves is " + colname );
	

Here use use S-Lang code to find out the name of the color used to draw curves. If the ChIPS state object has not been changed, then these commands would produce the following output:

  The color of curves is default
	

  chips> chips_color_name()
  black
  blue
  cyan
  default
  green
  magenta
  red
  white
  yellow
	

Since no value is given, the list of available colors is returned. This string may be stored in a variable:

  chips> hues = chips_color_name()
  chips> print(hues)   
  black
  blue
  cyan
  default
  green
  magenta
  red
  white
  yellow
	

As the names are separated by the newline ('\n') character, they can be easily separated using the S-Lang strchop() function:

  chips> colors = strchop( chips_color_name(), '\n', 0 )
  chips> print(colors[2])
  cyan
