Appendix A. Macros, Control Statements, Utilities, and Commands Syntax Reference 431
1st ed., 6/30/04 - 312579601
Single Optional Choice
If the first item is on the line below the base line, a single choice of items in the stack is
optional.
Defaults
Default values and parameters appear above the syntax diagram line. In the following
example, if a value is not specified with the command, Default Value is used by the HSC.
Some keyword parameters provide a choice of values in a stack. When the stack contains a
default value, the keyword and the value choices are placed below the baseline to indicate
that they are optional, and the default value appears above the keyword line. In the
following example, if the keyword is not specified with the command, Keyword(Default
Value) is used by the HSC.
Repeat Symbol
A repeat symbol indicates that more than one choice can be made or that a single choice
can be made more than once. The repeat symbol shown in this example indicates that a
comma is required as the repeat separator.
