Organization of this Manual
The guide contains the following chapters:
Chapter 1 Overview covers the basics of programming on MPE/iX. It
introduces the 900 Series HP 3000, HP-PA architecture, and MPE
operating systems. It describes the following topics on a high
level, suitable for management and programming purposes: MPE/iX
operating system features and fundamentals, user interface,
accounting structure, migration from the MPE V/E operating
system, and data conversion from MPE V/E.
Chapter 2 Utilities and Tools covers programmatic access to the MPE/iX
Command Interpreter and many other MPE/iX subsystems and
utilities.
Chapter 3 Program Development covers writing, compiling, linking, loading,
and running a program on MPE/iX. It discusses the
multiprogramming environment, error detection, and control
codes.
Chapter 4 Link Editor covers HP Link Editor/XL, which is a subsystem of
MPE/iX used to bring pieces of code together into executable
program files and maintain libraries of sharable code.
Chapter 5 Optimizing a Program covers the Optimizer subsystem of MPE/iX,
which improves program performance.
Chapter 6 File System describes the MPE/iX File System, including file and
record structure, File System services, file specifications,
file domains, data transfer, and file security.
Chapter 7 Data Management covers data management concepts and subsystems
on MPE/iX, including KSAM, ALLBASE/SQL, TurboIMAGE, and QUERY.
Conventions
UPPERCASE In a syntax statement, commands and keywords are
shown in uppercase characters. The characters
must be entered in the order shown; however, you
can enter the characters in either uppercase or
lowercase. For example:
COMMAND
can be entered as any of the following:
command Command COMMAND
It cannot, however, be entered as:
comm com_mand comamnd
italics In a syntax statement or an example, a word in
italics represents a parameter or argument that
you must replace with the actual value. In the
following example, you must replace filename with
the name of the file:
COMMAND filename
bold italics In a syntax statement, a word in bold italics
represents a parameter that you must replace with
the actual value. In the following example, you
must replace filename with the name of the file:
COMMAND(filename)
punctuation In a syntax statement, punctuation characters
(other than brackets, braces, vertical bars, and
ellipses) must be entered exactly as shown. In
the following example, the parentheses and colon
must be entered:
(filename):(filename)
underlining Within an example that contains interactive
dialog, user input and user responses to prompts
are indicated by underlining. In the following
example, yes is the user's response to the prompt:
Do you want to continue? >> yes
{ } In a syntax statement, braces enclose required
elements. When several elements are stacked
within braces, you must select one. In the
following example, you must select either ON or
OFF:
COMMAND { ON }
{ OFF}
[ ] In a syntax statement, brackets enclose optional
elements. In the following example, OPTION can be
omitted:
COMMAND filename [OPTION]
When several elements are stacked within brackets,
you can select one or none of the elements. In
the following example, you can select OPTION or
parameter or neither. The elements cannot be
repeated.
COMMAND filename [ OPTION ]
[ parameter]
Conventions (continued)
[...] In a syntax statement, horizontal ellipses
enclosed in brackets indicate that you can
repeatedly select the element(s) that appear
within the immediately preceding pair of brackets
or braces. In the example below, you can select
parameter zero or more times. Each instance of
parameter must be preceded by a comma:
[,parameter][...]
In the example below, you only use the comma as a
delimiter if parameter is repeated; no comma is
used before the first occurrence of parameter:
[parameter][,...]
|...| In a syntax statement, horizontal ellipses
enclosed in vertical bars indicate that you can
select more than one element within the
immediately preceding pair of brackets or braces.
However, each particular element can only be
selected once. In the following example, you must
select A, AB, BA, or B. The elements cannot be
repeated.
{ A} |...|
{ B}
... In an example, horizontal or vertical ellipses
indicate where portions of an example have been
omitted.
In a syntax statement, the space symbol shows a
required blank. In the following example,
parameter and parameter must be separated with a
blank:
(parameter) (parameter)
The symbol indicates a key on the keyboard. For
example, RETURN represents the carriage return key
or Shift represents the shift key.
CTRLcharacterCTRLcharacter indicates a control character. For
example, CTRLY means that you press the control
key and the Y key simultaneously.
