- 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.
- F1=Help appears on every menu in character-mode
Micro Focus software. It invokes a help screen describing the current menu.
F1=Help is not described in the documentation.
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.
- The books may refer you to the readme for details
specific to a particular UNIX platform.
- All command line formats and examples are for the standard UNIX shell,
the Bourne shell. If you are using another shell, see your UNIX documentation
for the appropriate formats.
- Where examples showing environment variables do not specifically show
them being exported to the shell, it is treated as implicit that they are
exported.
- Some keystrokes using function keys or the Alt or
Ctrl keys are not available on all UNIX platforms.The
UNIX Key Usage Chart
shows how the keystrokes shown in the documentation map onto actual
keystrokes.
