Conventions used in the Text

The following conventions are used throughout this manual to highlight certain features of the text:

• Command words are shown as a combination of uppercase and lowercase characters, using a different typeface from that used for normal text; for example, COMMandword. The uppercase part of the word (COMM in the preceding example) is the minimum permissible abbreviation. Where a command word is first introduced, or where its use is defined, it will usually be shown in bold type, thus

  COMMandword

• Command arguments are shown in lowercase italic type; for example, argument.

• Parts of the command enclosed between square brackets are optional; for example, ... [ignore this part of the command if not relevant]

• Examples of interactive input and output sequences are shown in a different typeface, thus

  Example of Input/Output Sequence Typeface

• Character strings which begin with the slash character / are either names of elements in the databases or the names of files in the operating system directories. For example, /ELEMENT or /filename.

  Character strings enclosed between angled brackets are the names of individual command syntax diagrams. For example, <diagram_name>.
