- 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.
