How to split text into hypertext topics
=======================================
Organizing information by idea units is one of the key features of hypertext.
We accomplish this by first using our SPLITTER program.
Load the ASCII First, load the ASCII file containing the text into your
file word processor. Then critically read the material by
mentally creating a short summary of each paragraph.
How to split Whenever the short summary text changes, enter codes for
ideas splitting (four equal signs ====) on a line before the
paragraph. Include on this line the filename and the
short description of the paragraph.
Run the SPLITTER The SPLITTER program reads these codes, then splits the
original file into numerous smaller files, with one
file per idea unit. The program looks for codes in the
file that identify the start of a new file, sections to
skip, and sections to merge.
Other outputs In addition, the program produces a file listing the
filenames and topics of each of the newly created
single-idea files.
In general, if you understand the subject of the text, you can split the
source ASCII text into 200 files per hour.
As a shortcut, you may first wish to OCR <FILE30 OCR> the index to the text,
then sort the index by page number to create a guide for splitting the file.
While appearing simple, the choice of filenames used has major consequences
at later stages in the development of hypertext systems. Here's why.
Automatic Although PC/MS DOS supports 64,000 files per directory,
subdirectory the access speed becomes very slow above 100 files
per directory. To solve this problem PC-Hypertext
automatically uses the first three characters of the
filename as a directory to the file. If the filename is
not found in the sub directory, then the program looks
in the current directory.
Filenames For example, you should define classes of filenames
that make effective use of the first three letters of
the filename to reduce file access time. For example, use
AAA1-AAA99, BBB1-BBB99, to have PC-Hypertext search
directory AAA for 99 files and directory BBB for 99
files.
While sounding slightly complex, I'll say from experience <FILE30 BUILDING>
that this is the only way to build hypertext systems that have rapid access to
thousands of files.
