The Clarion Professional Developer comes with an install program.
INSTALL creates a directory on your hard disk called \CLARION and
populates it with the files from the diskettes you received with
the Professional Developer package.
INSTALL asks permission to add \CLARION to your PATH statement in
your AUTOEXEC.BAT file and to change the FILES and BUFFERS values
in your CONFIG.SYS file.
When Clarion has been installed, it is executed as follows:
CLARION
(Enter)
This completes the Environment tutorial.
The Designer tutorial should be viewed next.
This tutorial operates in either MANUAL or AUTOMATIC viewing mode.
You can change the viewing mode at any time by pressing M for
MANUAL mode or A for AUTOMATIC mode.
When you are viewing in either mode, use the cursor right (
key to page forward, and the cursor left (
) key to page
backward. In MANUAL mode, the tutorial will wait for you page
forward. In AUTOMATIC mode, forward paging happens automatically.
You can speed up the tutorial by pressing the gray+ key, or slow
it down by pressing the gray- key.

F1 displays a help window. Clarion
help windows are context sensitive,
that is, they try to explain options
appropriate for the current process.
Some help windows display a menu of
help topics. Select a help topic
and press Enter to display its help
window. Esc removes a help window.
F2 displays the Clarion menu. The
menu is required because there are
more Clarion utility programs than
function keys.
The menu is part of each program,
so it is displayed immediately when
F2 is pressed.
The function keys can also be used
to execute Clarion utility programs.
The remaining function keys execute
the programs listed--exactly as if
they were executed from the Clarion
menu.
F7 is the "compile and test" key.
It executes Compiler and then, if
there are no errors, Processor.
Clarion "remembers" what it worked
on last--even between sessions. So
when you execute Editor, the input
file is already set to the file you
edited last.
Compiler defaults to the program you
edited last. Processor defaults to
the program you compiled last. And
Filer, Scanner, and Sorter default
to the file you used last.
These function keys work with the
Shift key to provide "immediate"
execution.
For example, F6 displays the base
page of Compiler with the default
input file filled in. Shift-F6
compiles the default input file
without stopping at the base page.

Compiler compiles Clarion source code into Clarion
processor code. Clarion processor code is executed
by Processor (without a link step) and is converted
by Translator into standard object code.
Converter imports Clarion files from and exports
Clarion files to: Dbase II and Dbase
, DIF,
and BASIC (comma delimited) files.
Designer generates source code for entire applications
by combining screens and reports painted on the video
monitor with a complete data dictionary.
Director is a DOS shell that accepts DOS commands and
displays the sub-directories and files in the current
directory. Control keys can be used to manipulate
these directory entries.
Editor is used to create and change source program
files. Editor knows the Clarion language and also
supports keyboard macros, search and replace with
wildcards, line or character blocks, zone insert,
and multiple windows.
Filer creates an empty Clarion file from a
source file layout. If a file layout changes,
Filer rearranges each record from the old file
to match the new record layout.
Helper creates help files from windows painted on
the video monitor. Help windows are displayed by
a Clarion program whenever the F1 key is pressed.
Processor executes Clarion processor code without linking.
A debugging window can be displayed by pressing the Ctrl
and Break keys at the same time (Ctrl-Break). This window
watches variables, sets resume and break points, traces,
single cycles, and scrolls source code.
The Reporter creates database and report definitions from
Dbase, ASCII, and Clarion data files which can then be used
to produce reports to the screen, a disk file, or a printer.
Scanner displays a Clarion file like a spread-sheet
(each record in a row and each field in a column).
Records can be added, changed, and deleted. Column
sequence and format can be customized and saved.
Sorter sorts, combines, backs up, restores,
compresses, and reorganizes Clarion files.
Tailor customizes the Clarion utility programs
for colors, keyboard options (such as beep and
video timeout), source code column conventions
and print options.
Translator creates standard object (.OBJ) files from processor
code created by Compiler. Translator also asks permission to
create an auto response file and execute LINK or PLINK in order
to create a standard executable (.EXE) file.
This is the Clarion menu. Each of the Clarion
utility programs can be executed from this menu.
Crossrefer builds a cross-reference listing of the global
data in an application. The listing shows where a label
is declared and every place it is used.
