The capabilities of tpr are specified in the attached Request Summary. Numerical values are denoted there by n or +n, titles by t, and single characters by c. Numbers denoted +n may be signed + or -, in which case they signify relative changes to a quantity, otherwise they signify an absolute resetting. Missing n fields are ordinarily taken to be 1, missing t fields to be empty, and c fields to shut off the appropriate special interpretation.
Running titles usually appear at top and bottom of every page. They are set by requests like
.he 'part1'part2'part3'
Part1 is left justified, part2 is centered, and part3 is right justified on the page. Any % sign in a title is replaced by the current page number. Any nonblank may serve as a quote.
The options currently available are:
In addition, ``-'' in the input file list indicates that standard input is to be opened and read.
Although tpr is written in C, it will probably be utterly frozen because of the archaic convention of control lines and text lines and paucity of structured directives.
