_NONBLANKLINESALL — Returns the number of non-blank lines in all files processed by the last call to WORDS.

Syntax:
%_NONBLANKLINESALL

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

If the WORDS command has not been called, this variable returns the value N/A.
