_SENTENCESALL — Returns the total number of sentences in all files processed by the last call to WORDS.

Syntax:
%_SENTENCESALL

A ‘sentence’ is a word or series of words ending with a period, exclamation mark, or question mark. Divide %_SENTENCEWORDSALL by %_SENTENCESALL to get the average sentence length.

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