Syntax Flow Diagrams

Syntax is illustrated using flow diagrams. These can include the following elements:

•syntax – the diagram itself.

•items – individual elements inside the diagram. Items can be keywords, variables, delimiters, operators, fragment references, and separators.

•groups – a collection of items or other groups.

The following sections describe syntax flow diagram features and include some generic examples.

Specifying Commands

Commands are composed of command names, keyword parameters, and positional parameters. Command names initiate command execution, keyword parameters are operands that contain keywords and their related values, and positional parameters are operands that are identified by their position in the command string rather than by keywords.

•Keyword parameters can be specified in any order. The HSC accepts (tolerates) multiple occurrences of a keyword. The value assigned to a keyword reflects the last occurrence of a keyword within a command.

•Positional parameters must be entered in the order shown in the syntax diagram.

•Uppercase letters indicate the minimum abbreviation for the command name, keyword, or positional parameter.

Variables

Variables are italicized.

Delimiters

If a comma (,), a semicolon (;), or other delimiter is shown with an element of the syntax diagram, it must be entered as part of the statement or command.
