DSR routinely inserts an extra expandable space after a period (.), colon (:), question mark (?), or exclamation point (!) that is followed by the usual end-of-word space. The Period flag (+) lets you specify the extra space following other characters. If the flag is turned on and .FILL is in effect, an extra space occurs when the flag (+) is inserted directly after the character. You must, however, insert the end-of-word space after the flag if it is to be effective. For example, if you have a complete sentence enclosed in quotation marks or parentheses, you may want an extra space after the closing quotation mark or parenthesis.

Recognition is turned off. To turn on recognition, you must use the .FLAGS PERIOD command.
