The following table explains the text formatting conventions used in this manual:

Text formatting Convention
Bold Bold characters indicate text in a window, other than the window title. Such text includes menus, menu options, buttons, radio box options, or explanatory labels. For example:
  • From the File menu, choose Open.
  • Click the Cancel button.
  • In the Enter name entry box, type your name.
Italic Italic characters indicate a placeholder for some actual text to be provided by the user or system. For example:
  • Write the command as follows:
    copy source-file target-file
  • The following message appears:
    A file was not found. (file = file-name)
Italic characters are also used for emphasis. For example:
  • Do not delete the configuration file.
Monospace Monospace characters indicate text that the user enters without change, or text (such as messages) output by the system. For example:
  • At the prompt, enter dir.
  • Use the send command to send mail.
  • The following message is displayed:
    The password is incorrect.

The following table explains the symbols used in this manual:

Symbol Convention
| In syntax explanations, a vertical bar separates multiple items, and has the meaning of OR. For example:
A|B|C means A, or B, or C.
{ } In syntax explanations, curly brackets indicate that only one of the enclosed items is to be selected. For example:
{A|B|C} means only one of A, or B, or C.
[ ] In syntax explanations, square brackets indicate that the enclosed item or items are optional. For example:
[A] means that you can specify A or nothing.
[B|C] means that you can specify B, or C, or nothing.
... In coding, an ellipsis (...) indicates that one or more lines of coding have been omitted.
In syntax explanations, an ellipsis indicates that the immediately preceding item can be repeated as many times as necessary. For example:
A, B, B, ... means that, after you specify A, B, you can specify B as many times as necessary.
() Parentheses indicate the range of items to which the vertical bar (|) or ellipsis (...) is applicable.
{{ }} A double pair of curly brackets encloses multiple items, all of which you can specify multiple times as a unit.
Example: {{pdbuffer -a option-name}}
This example indicates that you can specify the above multiple times as follows:
pdbuffer -a option-name
pdbuffer -a option-name
~ A swung dash precedes the attributes of a user-specified value.
<< >> A double pair of angle brackets encloses the default value assumed by the system when the specification is omitted.
< > A single pair of angle brackets encloses the syntax element notation for a user-specified value.
(( )) A double pair of parentheses encloses the permitted range of values that can be specified.
[Figure] [Figure] Round up the result to the next integer.
Example: The result of [Figure]34 [Figure] 3[Figure] will be 12.
[Figure] [Figure] Discard digits following the decimal point.
Example: The result of [Figure]34 [Figure] 3[Figure] will be 11.
MAX Select the largest value as the result.
Example: The result of MAX(3 [Figure] 6, 4 + 7) will be18.
MIN Select the smallest value as the result.
Example: The result of MIN(3 [Figure] 6, 4 + 7) will be 11.

Conventions: Version numbers

The version numbers of Hitachi program products are usually written as two sets of two digits each, separated by a hyphen. For example:

The version number might be shown on the spine of a manual as Ver. 2.00, but the same version number would be written in the program as 02-00.
