How to understand the cross-links in ASCII files
================================================
PC-Hypertext is a hypertext system allowing users to browse <file56 METHODS>
through networks of information in non-linear ways.
PC-Hypertext uses information in angle brackets, such as <file2 CALLS>, to
indicate jumps to other files or programs. This format makes all links
traceable on paper as well as in the program.
PC-Hypertext includes two methods to select angle-bracket links. They are:
Up/Down Arrows -- Move a text highlighter to the next or previous
============== cross-reference. Press Enter or F4 to display file
<file0 START>. Press F3 to return to the previous file.
Plus/Minus Keys -- Move a text highlight across each line of text. If the
=============== line selected contains an angle bracket jump, press
Enter or F4 to display that file. More <file0A>
That covers the methods of selecting and making cross-reference jumps in
ASCII files. From the viewpoint of a developer of hypertext systems, there
are several ways to put the actual angle brackets in the ASCII files.
While I prefer to embed cross-references, other ways to include links are:
Left-margin -- The left margin in scholarly work often contains
=========== layers of cross-references and margin commentary
notes. See more <file5>
Embedded links -- Cross-reference links can be directly embedded in the
============== text. See more <file6>
Leading links -- Putting the cross-reference links at the beginning of
============= key files helps users select only the information
components needed. Read about star hypertext <file33>
Right-margin -- As the ASCII display in PC-hypertext supports text
============ widths up to 255 columns, the angle bracket
cross-references to ideas can be place off the screen.
For example, CD-ROMs are important. <file20>
Footnote links -- If the angle brackets interfere with reading, use a
============== numbered reference (a) to the footnote jump at the end
of the file. See footnotes.
