Conventions

The following conventions apply to the syntax diagrams in this appendix:

• All diagrams have abbreviated names. Such names are composed of lowercase letters enclosed in angled brackets, for example. <assign>. These short names, which are used for cross-referencing purposes in the text and within other syntax diagrams, are supplemented by fuller descriptions where they are not self-explanatory.

• Commands to be input from the terminal are shown in a combination of uppercase and lowercase letters. In general, these commands can be abbreviated; the capital letters indicate the minimum permissible abbreviation.

  Note:
  The convention does not mean that the second part of the command must be typed in lowercase letters; commands may be entered in any combination of uppercase and lowercase letters.

  ELElist

may be input in any of the following forms:

ELE
ELEl
ELEli
ELElis
ELElist

Commands shown wholly in uppercase letters cannot be abbreviated.

• Syntax diagrams are generally read from top left to bottom right.

• Points marked with a plus sign (+) are option junctions which allows the user to input any one of the commands to the right of the junction. Thus

         >---+--- ABC -----.
             |             |
             |--- PQR -----|
             |             |
             |--- <dia> ---|
             |             |
             ‘-------------+--->
  

Type in ABC or PQR or any command allowed by the syntax given in diagram <dia> or just press RETURN to get the default option.

• Points marked with an asterisk (*) are loop back junctions. Command options following these may be repeated as required. Thus

                .-------------.
               /              |
          >---*--- option1 ---|
              |               |
              |--- option2 ---|
              |               |
              ‘--- option3 ---+-->
  

permits any combination of option1 and/or option2 and/or option3 to be used (where the options may define commands, other syntax diagrams, or command arguments) and may form an exception to the rule of reading from top left to bottom right.

The simplified format

             .---------.
            /          |
        >---*--- name -+--->

Type in a list of AVEVA E3D Design names, separated by at least one space.
