If paragraphs in your file consist of a sequence of lines beginning in the same column and are separated from other paragraphs by at least one blank line, the following macro indents a paragraph to the next tab stop:
para_indent:=_pwbboxmode Meta Mpara Down Begline Arg \
Meta Ppara Up Begline Tab Insert
This macro starts with the predefined PWB macro _pwbboxmode to set box selection mode, then creates a box selection from the beginning of the paragraph to the end, one tab stop wide. The Insert function inserts spaces in the selection.
