<Chapter 15:  Help>
     The entire PEP manual is available for on-line viewing via PEP's
indexed HELP system. At any time, when you are using PEP, you can press F1
(or click on the [?]-button) to activate HELP. A new screen layout is then
created containing four windows: a prompt window, a menu window, a graphic
window and a document window. The document window displays a portion of
the PEP manual text. If there is an illustration accompanying the
displayed text, it will appear in the graphic window. See <[FIG29]>.

     The HELP system is context sensitive. The portion of the document
initially displayed depends on the state of PEP when HELP is invoked. PEP
attempts to display the portion of the document relevant to your current
operation. PEP's choice depends on the current menu being displayed and on
the last command executed. In addition, if you want information about a
particular command, you can use the cursor to highlight that command and
then press F1. By pressing F1 while you are in HELP, you can display
documentation on the HELP system itself. In other words, you will display
this chapter of the manual.

     While the HELP system is active, the NumPad keys on the keyboard are
detached from the cursor. (The cursor can only be moved via the mouse).
Instead the NumPad keys control the text displayed in the document window.
The up arrow (or left arrow) moves the displayed text backwards one line.
The down arrow (or right arrow) moves the displayed text forward one line.
PGUP and PGDN move the text display backwards or forwards one page. HOME
and END position the text at the start and end of the current chapter,
respectively.

     When the discussion at one place in the document refers to
information located in a different section, there will often be a
cross-reference mark in the HELP display at that place. This mark consists
of a section number in square brackets, and is always highlighted. If you
have a mouse, you can access the referenced section by positioning the
cursor on the cross-reference mark and pressing the left mouse button.
This is called clicking on the reference. If you do not have a mouse, you
can use the GOTO command <[15.8]> to display the new section.

     Illustrations appear in the document text as figure references. These
are highlighted strings of the form "FIGxx" appearing in square brackets,
where "xx" is the figure number. (The figures are objects in the file
DOCFIGS.PDL.) You can click on a figure reference to display that figure
temporarily in the document window, pressing ESC when you want to restore
the normal document display. The same operation can be performed with the
ZOOM command <[15.9]>.

<Section 15.1:  Up>
     The UP command moves the document display backwards to display the
previous page of document text. The same function can be invoked by
pressing the page up key, PGUP. This command only moves within the
currently displayed chapter. To move to another chapter use the GOTO
command <[15.8]>.

<Section 15.2:  Top>
     The TOP command moves the document display to the top of the current
chapter. The same function can be invoked by pressing the HOME key.

<Section 15.3:  Down>
     The DOWN command moves the document display forwards to display the
following page of document text. The same function can be invoked by
pressing the page down key, PGDN. This command only moves within the
currently displayed chapter. To move to another chapter use the GOTO
command <[15.8]>.

<Section 15.4:  Bottom>
     The BOTTOM command moves the document display to the bottom of the
current chapter. The same function can be invoked by pressing the END key.

<Section 15.5:  Contents>
     The CONTENTS command displays the table of contents of the PEP
manual. There is one entry for each section of the manual. Each entry
includes the section number and the section title. The HELP system treats
the table of contents like any other chapter of the document. All of the
HELP commands (UP, DOWN, SEARCH, REPEAT, etc.) are equally applicable to
the table of contents. When you have located the section that you wish to
consult, simply click on its section number in the table of contents to go
to that section of the document. You can also use the GOTO command
<[15.8]> to display that section.

<Section 15.6:  Search>
     With the SEARCH command you can search the current chapter (or table
of contents) for the first occurrence of a given word. The search begins
at the top of the current chapter. The search ignores the distinction
between upper and lower case; either case of a letter counts as a match
for that letter. If you want to find additional occurrences of the same
word use the REPEAT command described below.

     To operate the SEARCH command press the command letter, type in the
word you want to search for and press RETURN. PEP will locate the first
occurrence of the string you typed, and will display it highlighted in the
document window.

     The SEARCH command is particularly useful for searching the table of
contents to find the sections referring to a particular topic. See the
CONTENTS command described above.

<Section 15.7:  Repeat>
     After you have used the SEARCH command to find the first occurrence
of a given word, you can use the REPEAT command to find subsequent
occurrences of the same word within the current chapter. Press the command
letter to locate the second occurrence. Continue pressing the command
letter to find the third and subsequent occurrences.

<Section 15.8:  Goto>
     To display a particular chapter or section in the document window use
the GOTO command. Press the command letter, then type in the desired
section number and press RETURN. The designated section will be displayed
in the document window.

     Section numbers consist of one, two, or three numbers separated by
periods. For example, 10, 10.6, and 10.6.3 are possible sections numbers.
The first number is the chapter number; the second is the section number
and the third the sub-section number. To find the section number of the
section that you want to consult, use the CONTENTS command <[15.5]> to
display the table of contents of the manual.

<Section 15.9:  Zoom>
     The ZOOM command temporarily replaces the document window display
with a magnified copy of the illustration displayed in the graphics
window. Press the command letter a second time (or press ESC) to restore
the document text display.
