- Enter refers to the carriage return or Enter key.
Where commands to be typed are shown, the Enter key is not explicitly shown; it
is treated as implicit that Enter must be pressed at the end of the line.
- Hexadecimal numbers are enclosed in quotation marks and preceded by a
lower-case "x" or "h"; for example, x"9D", h"03FF". The "x" is used when the
hexadecimal number represents a character string; the "h" when it represents a
numerical value.
- PIC X is used rather than PIC 99 with the COMP-X and COMP-5 data types.
Unlike PIC 99, PIC X shows the length of the data item and so demonstrates more
clearly the use of COMP-X, which is to define a binary item of the specified
number of bytes.
- Keytops and menu choices are emboldened within the text.
- In some environments, you might notice that what appears on your screen
differs in minor ways (for example, version numbers) from that illustrated in
this book. This will not affect the operation of your software.
- The keys described in this book are not
available in all environments. When there is a reference to use of a key such
as a status or function key, this refers to the logical press and release of
this key, rather than physical keystroke. If your environment does not support
the key given, please refer to your accompanying Read Me for the
equivalent key.
- The term "window" refers to a delineated
area on the screen, normally smaller than the full screen. The term "Windows"
refers to Microsoft Windows 3.1 or later.
- On-line help is not described in the
documentation. Select Help from the menu or press the
Help button on a dialog box to see context sensitive help
information.
The notation used to describe the format of command lines is as follows:
- Words printed in italics are generic terms representing names to be
devised by you.
- Words printed in nonitalic characters are the actual words you must
enter. You must type them in upper or lower case as shown.
- Material enclosed in square brackets [ ] is optional.
- When material is enclosed in braces { }, you must choose from the
options within them. If there is only one option in the braces, the braces
indicate repetition.
- The ellipsis (. . .) follows { } or [ ] and means you can repeat the
material in the { } or [ ]. The number of repetitions allowed is unlimited
unless otherwise stated. If the ellipsis is used with [ ] the material can be
omitted altogether.
- If a command line does not fit across the page, it is continued on the
next line; the continuation line is indented.
- Command line options can be specified as
/option or -option.
