- SYNOPSIS SYNOPSIS
- nro n n pxx v b mmfile ifile ofile nro [-n] [+n] [-pxx] [-v] [-b] [-mmfile] ifile ... [>ofile]
-
- DESCRIPTION DESCRIPTION
- ___ NRO is a text processor and formatter based on the design
- Software Tools provided in "Software Tools" by Kernighan and Plauger. The
- ________ text and commands found in the ifile(s) are processed to
- generate formatted text. The output may be directed into a
- _____ file or to the printer if ofile is present in the command
- line; otherwise, the output will appear at the user
- P console. Directing the output to the special filename, $P,
- will cause the output to be sent to the printer.
-
- _ _ The +n option causes the output to start with page n. The
- _ _ -n option causes the output to stop after page n.
-
- _ The -v option prints the version number to the console.
-
- _ The -p option causes the output to be shifted to the right
- __ po by xx spaces. This has the same effect as the .po command.
-
- _ The -b option allows backspaces to appear in the output text
- when underlining or overstriking. This has the same effect
- bs as the .bs command with a non-zero argument.
-
- _ _____ The -m option processes the file mfile for macro
- definitions. Note that files processed in this way should
- contain only macro definitions, no immediate output should
- be generated from this file.
-
- Commands typically are distinguished by a period in column
- one of the input followed by a two character abbreviation
- for the command funtion. The abbreviation may then be
- followed by an optional numeric or character argument. The
- numeric argument may be an absolute value such as setting
- the right margin to a particular column, or the argument may
- be preceded by a plus sign or a minus sign to indicate that
- the parameter should be modified relative to a previous
- setting. The following commands are recognized:
-
- .bo - causes the following lines of text to appear in
- boldface. The optional argument specifies the number
- of lines to be typed in boldface. Boldface and
- underlining are mutually exclusive features. The
- appearance of a boldface command will cause any
- underlining to cease.
-
- .bp - causes succeeding text to appear at the top of a new
- page. The optional argument specifies the page number
- for the new page. The initial value is one and the
- default value is one more than the previous page
- number.
-
- .br - causes succeeding text to start on a new line at the
-
-
- -1-
-
-
- NRO (1) MS-DOS Version 3.2 NRO (1)
-
-
- current left margin. There is no numeric argument for
- this command.
-
- .bs - enables or disables the appearance of backspaces in
- the output text. Underlining and boldface options are
- implemented by inserting character - backspace -
- character combinations into the output buffer. This
- is fine for devices which properly recognize the
- backspace character. Some printers, however, do not
- recognize backspaces, so the option is provided to
- overprint one line buffer with another. The first
- line buffer is terminated with just a carriage return
- rather than the carriage return - linefeed
- combination. A zero argument or no argument to the
- backspace command removes backspaces from the output.
- A non-zero argument leaves them in the output. The
- default is to remove backspaces.
-
- ___ .cc - changes the NRO command character to that specified by
- the character argument. If no argument is provided,
- the default is a period.
-
- .ce - causes the next line of text to appear centered on the
- output. The optional argument specifies if more than
- one line is to be centered.
-
- .de - causes all text and commands following to be used to
- en define a macro. The definition is terminated by a .en
- command. The first two characters of the argument
- de following the .de command become the name of the new
- command. It should be noted that upper and lower case
- arguments are considered different. Thus, the
- PP pp commands .PP and .pp could define two different
- macros. Care should be exercised since existing
- commands may be redefined.
-
- A macro may contain up to ten arguments. In the macro
- definition, the placement of arguments is designated
- by the two character sequences, $0, $1, ... $9. When
- the macro is invoked, each argument of the macro
- command line is substituted for its corresponding
- designator in the expansion. The first argument of
- the macro command is substituted for the $0 in the
- expansion, the second argument for the $1, and so
- forth. Arguments are typically strings which do not
- contain blanks or tabs. If an argument is to contain
- blanks, then it should be surrounded by either single
- or double quotes.
-
- .cu - causes the next line(s) of text to be continuously
- ul underlined. Unlike the underline command (see .ul)
- which underlines only alphanumerics, continuous
- underlining underlines all printable characters. The
- optional argument specifies the number of lines of
- text to underlined. Any normal underlining or
- boldface commands currently in effect will be
- terminated.

-
-
- .ef - specifies the text for the footer on even numbered
- pages. The format is the same as for the footer
- fo command (see .fo).
-
- .eh - specifies the text for the header on even numbered
- pages. The format is the same as for the footer
- fo command (see .fo).
-
- .en - designates the end of a macro definition.
-
- .fi - causes the input text to be rearranged or filled to
- obtain the maximum word count possible between the
- previously set left and right margins. No argument is
- expected.
-
- .fo - specifies text to be used for a footer. The footer
- text contains three strings seperated by a delimiter
- character. The first non-blank character following
- the command is designated as the delimiter. The first
- text string is left justified to the current
- in indentation value (specified by .in). The second
- string is centered between the current indentation
- value and the current right margin value (specified by
- rm .rm). The third string is right justified to the
- current right margin value. The absence of footer
- text will result in the footer being printed as one
- blank line. The presence of the page number character
- pc (set by .pc) in the footer text results in the current
- page number being inserted at that position. Multiple
- occurrances of the page number character are allowed.
-
- .he - specifies text to be used for a header. The format is
- fo the same as for the footer (see .fo).
-
- .in - indents the left margin to the column value specified
- by the argument. The default left margin is set to
- zero.
-
- .ju - causes blanks to be inserted between words in a line
- of output in order to align or justify the right
- margin. The default is to justify.
-
- .ls - sets the line spacing to the value specified by the
- argument. The default is for single spacing.
-
- .m1 - specifies the number of lines in the header margin.
- This is the space from the physical top of page to and
- including the header text. A value of zero causes the
- header to not be printed. A value of one causes the
- header to appear at the physical top of page. Larger
- argument values cause the appropriate number of blank
- lines to appear before the header is printed.
-
- .m2 - specifies the number of blank lines to be printed
- between the header line and the first line of the
- processed text.
-
- .m3 - specifies the number of blank lines to be printed
-
-

-
-
- between the last line of processed text and the footer
- line.
-
- .m4 - specifies the number of lines in the footer margin.
- m1 This command affects the footer the same way the .m1
- command affects the header.
-
- .ne - specifies a number of lines which should not be broken
- across a page boundary. If the number of lines
- remaining on a page is less than the value needed,
- then a new output page is started.
-
- .nf - specifies that succeeding text should be printed
- without rearrangement, or with no fill. No argument
- is expected.
-
- .nj - specifies that no attempt should be made to align or
- justify the right margin. No argument is expected.
-
- .nr - causes the value of a number register to be set or
- modified. A total of twenty-six number registers are
- available designated @na through @nz (either upper or
- lower case is allowed). When the sequence @nc is
- imbedded in the text, the current value of number
- register c replaces the sequence, thus, such things as
- paragraph numbering can be accomplished with relative
- ease.
-
- .of - specifies the text for the footer on odd numbered
- pages. The format is the same as the footer command
- fo (see .fo).
-
- .oh - specifies the text for the header on odd numbered
- pages. The format is the same as the footer command
- fo (see .fo).
-
- .pc - specifies the page number character to be used in
- headers and footers. The occurrance of this character
- in the header or footer text results in the current
- page number being printed. The default for this
- character is the hash mark (#).
-
- .pl - specifies the page lenght or the number of lines per
- output page. The default is sixty-six.
-
- .po - specifies a page offset value. This allows the
- formatted text to be shifted to the right by the
- number of spaces specified. This feature may also be
- invoked by a switch on the command line.
-
- .rm - sets the column value for the right margin. The
- default is eighty.
-
- .so - causes input to be retrieved from the file specified
- by the command's character string argument. The
- contents of the new file are inserted into the output
- stream until an EOF is detected. Processing of the
- original file is then resumed. Command nesting is

- allowed.
-
- .sp - specifies a number of blank lines to be output before
- printing the next line of text.
-
- .ti - temporarily alters the indentation or left margin
- value for a single succeeding line of text.
-
- .ul - underlines the alphanumeric text in the following
- line(s). The optional argument specifies the number
- of lines to be underlined. Underlining and boldface
- are mutually exclusive features. The appearance of an
- underline command cancels any existing boldface
- operations.
