_NONBLANKLINES — Returns the number of non-blank lines in the last file processed by WORDS.

Syntax:
%_NONBLANKLINES

A line which contains only whitespace characters such as spaces or tabs is considered blank. Subtract %_NONBLANKLINES from %_LINES to get the number of blank lines.

If the WORDS command has not been called, or if there was any error reading the last file, this variable returns the value N/A.
