op.paragraph

specifies the number of spaces to indent the first line of a paragraph.

To utilize this command, begin each paragraph with exactly one space. This affects an output with an indent of 'number.spaces', and a blank line between each paragraph.

Only the first line of the paragraph is indented. Subsequent lines are output at the left margin. When 'number.spaces' is negative, the first line of the paragraph is output that many spaces relative to the left of the left margin.

The '.xparagraph' command terminates paragraph mode.
