I use this as a stored template, readstatus().

Note that #percentread is integer and #readinglist is series-like managed with the Reading List plugin.

program:

	if $$#percentread >=#1 && $$#percentread <=#99
	then 'currentlyreading' 

	elif "To Be Read" in $#readinglist && $$#percentread ==#0
	then 'toberead' 

	elif $$#percentread >=#100
	then 'read' 

	elif $$#percentread == 'None'
	then 'undefined' 

	elif $$#percentread >=#0
	then 'unread' 

	fi

This allows the user to use readstatus() == 'currentlyreading' or '(unread|toberead)' in readstatus() in templates rather than checking the columns directly.

It would probably also work as a composite column.
