% The following macro is called from SELECT.STY. (Please, try FAIRYSEL.TEX,
% if you want to see an example, how to use SELECT.STY.) The description
% inside this comment is used for beginners who would like to change this
% file to suit their personal needs. TeXperts would understand this simple
% code without my explanations.
%
% You need to do only two things to make this file work for you. First, you
% might like to change \unitlength to some other unit. It is not advisable to
% use large units as 1cm or 1in or even larger because you would be unable to
% control positionning. The second think, which might require modification,
% is the definition of the {picture} environment. The form of the command
% applicable to this file is:
%
%      \begin{picture}(W,H)(0,-Y)
%
% Here, W and H are the available width and height of the paper,
% respectively (expressed in terms of \unitlength). Assuming that the area of
% height T on the top of the paper is not available (due to printer hardware)
% when feeding it manually, then Y = H + T. For STAR LC 24--10, H = 260mm,
% T = 20mm, thence using \unitlength of 1mm we get
%
%      \begin{picture}(210,260)(0,-280)
%
% You may measure the available space used by your printer by printing
% TESTPAGE.TEX, which, I hope, is widely available.
%
% Now you want to commence filling-in your form. You can print only one
% page per file. The name of the fill-in document is transferred between
% \LaTeX passes using the mechanism of SELECT.STY. You have to delete
% FILLFORM.SEL if you want to work with other document. The fill-in document,
% however, remains on the hard disk. If you enter the name of the existing
% document, it is loaded from the disk and doesn't allow interactive input.
% This enables you to prepare and preview several pages of fill-in documents,
% preview them and then print them.
%
% As mentioned above, the input is interactive within the first pass. The
% input is stored in the file of the specified name and then processed. If you
% are not satisfied with what you entered, you may edit the file without the
% necessity of re-typing all entries.
%
% The first question, you are asked, is the request for the name of the
% fill-in document. Please notice that the macrocode adds the `default'
% extension `.frm'. You may specify path (but use `/' as separators, not
% MS--DOS's `\'!) but extension must not appear in your entry. If the file
% exists, it is loaded. If not, interactive questions are asked.
%
% Take the form to be filled in and your ruler. you must supply `Left
% distance', which is the distance of the lower left corner of the input
% field from the left edge of the paper (of course in \unitlength), `Upper
% distance', which is the distance of the lower left corner of the input
% field from the upper edge of the paper, `Width', which is the width of the
% input field, and `Height', which is the height of the input field.
% Afterwards, the file requests the alignment. The text is always aligned
% with the bottom of the input field. As default, it is centered. You can
% enter `l' for left or `r' for right alignment, respectively. Entering the
% text needs some precautions. Your interactive input is written to the file
% and then processed using standard \input command. Therefore, all control
% sequences (those words starting with `\') must be preceded by `\string',
% otherwise \TeX would run out of memory. I this case, you do not need Wizard
% as suggested in the error message. You just need to use \string, e.g.
% \string\today for date. Remember that \TeX eats up all spaces after the
% control sequence. Thence `\string\it John Wilkiesbood' will produce
% `undefined control sequence \itJohn' when the frm-file is processed. To
% prevent such errors, you must enter `\string\it{}John Wilkiesbood'. Anyway,
% once you make such an error, the easiest way to recover is to edit the
% frm-file and re-\LaTeX FILLFORM.TEX.
%
% Type `y' if there are more items to be input or `n' if everything is
% done. Afterwards, the file is closed and then input and processed. Just
% before inputting your file, FILLFORM.SEL asks the question:
%
%   Show frames? (y/n)
%
% If you answer `y', all entries will be framed. Thence you can verify in
% preview that all entries fit inside the space available. When everything is
% O.K., rerun FILLFORM.TEX without frames.
%
% If there is something wrong in your fill-in document, edit the frm-file
% and then rerun FILLFORM.TEX. Your document will automatically be loaded.
