Hi!

  Here goes a new version of the formatter to accept ANY number of pages and
that doesn't requires the comment %%Page: to be printed. Don't use it with the Pageview though. The older version should be used with it.

(Hi everybody: \015 \015 \
\011 There is someboby that has asked me for a copy of the PostScript \
formatter I've written. So I send a copy of it. It is really a modification of \
a program in the Cookbook. \(Program 12 / A simple line breaking algorithm\). \
It also contains the program 18 to add accents to foreign languages. \015 \
\011 There are some very important variables to define the format of the \
resulting text. They are \(to change, locate /<variable name>\): \015 \015 \
\011 - yinic, inicial "y" value; \015 \
\011 - tamanho_linha, the size of the line; \015 \
\011 - tabwidth, the size of the tab spacing; \015 \
\011 - xrightmargin, the right margin; \015 \
\011 - ydec, the amount decremented from yline at each new line; \015 \
\011 - yline, variable that has the current line "y" value; \015 \
\011 - maxbreakwidth, maximal admitted space between words; \015 \
\011 - maxlinesinpage, maximal number of lines in a page. \015 \
\015 \011 In adittion there are values that should be set into the commands, \
like the size of the characters. It should be set in the "scalefont" command. \
\015 \011 Although this example is pretty clear, some comments should be done \
to use it correctly. The text to be formatted must be into a string pushed \
onto the stack as a parameter to the BreakIntoLines procedure. Inside this \
string is imperative the use of white space followed by a back slash \
in each line end. If the formatting fails this is most of the times the main \
reason. Inside this string many commands can be used to indicate special \
format characteristics. These commands are octal numbers, which in PostScript \
are represented as a backslash followed by three octal digits. It is \
imperative to separate these commands from the text before and after by one \
space. This is the second main source of errors. These commands should not be \
confused with the special characters also represented as octal numbers, \
that CAN be joined to the words. These commands are: \015 \015 \
\011 - \134001, Breaks the line and justify; \015 \
\011 - \134011, TAB character. Most used as paragraph; \015 \
\011 - \134015, CR character. Breaks the line, but doesn't justify. \015 \
\015 \011 Page breaks are automatic, but there must be at least the same \
number of "%%Page:" comments as the number of pages of the formatted text \
IF YOU USE Pageview!!! If you don't use Pageview, that is, you would only \
print the formatted file, you don't need anymore this. This new version does \
it automatically. With this new version the text can be of any size that it \
will break the pages properlly when printing. The version to the Pageview \
then remains reserved only to see the formatted text on the screen or to \
debug when altering the program. \015 \
\011 The names of the special characters to make accents in foreign \
languages, to change them, can be found \
in the red book under the title of "Codes and Names" in the appendix A. \
Observe the \134scandvec array and the octal codes on the left. On the \
right there are these names of characters which should be coded inside the \
text as the octal code \(ex: \362 is represented by \134362 inside the text\). \
Bug reports please mail to stolte@irit.fr. \
It is not what it could be called an \
ultimate text formatter and have its limitations. I count on you all to \
extend this program to a more complete set of comands to turn it \
more  flexible and usefull. Any changing should be mailed to me. \
\015 \015  Abra\325os, \015 \015 Nilo Stolte. \
\015 \015 PS: this text surpasses one page on purpose! )
