READ Commands

You will see a menu of commands. READ works in two major ways, by locating sections of a document by content, and by working with marks in the document set by the user while viewing it (just like attaching paper clips to pages, inserting bookmarks, or dog-earing pages). There is a list of all ``referenced'' sections known to READ at any time. Keep these ideas in mind as you read the explanations of the commands (it is a good idea to play around with the program as you read these sections).

Add word to references.

You're asked for a word. All sections in which that word appears are added to the list of referenced sections. (That is, in the logical sense, they are OR'ed.)

And word with references.

You're asked for a word. All sections in which that word appears, and which have been previously marked as being referenced are marked as referenced. Other previously marked references are cleared.

Subtract word from references.

You're asked for a word. All sections in which that word appears are removed from the reference list (if present).

Clear references.

All references are cleared from the reference list.

List references.

The titles of all sections referenced are listed. If more than a screen full of titles are referenced, the user can type ``M'' to see the next screen-load. ``C'' returns to the command menu.

Show referenced text.

The text from the document is displayed for referenced sections, starting with the first referenced. If the text is more than a screen full, typing ``M'' will show the next screen-load. Typing ``N'' shows the next reference, if any. Typing ``C'' gets back to the command menu. ``+'' advances to the next section in the document (referenced or not), and ``-'' backs up to the previous section. ``S'' sets a mark on the section, and ``U'' unsets (i.e., clears) the mark.

List section titles.

All section titles are displayed. ``M'' gets the next screen full, and ``C'' gets back to the command menu.

Select marked sections.

All sections which have been marked by the user (with the ``S'' key while viewing the text) are added to the list of referenced sections. To view just the marked sections, clear the reference list, then select marked sections.

New document.

The user is asked for a new document name, and viewing of that document is begun.
