Syntax diagram color-coding
To help you navigate the syntax, advanced SELECT prototyping uses a tabbing and color-coding scheme.
You can tab to those parts of the syntax where you are able to either make a choice or enter a variable. You cannot tab to a required keyword.
Advanced SELECT prototyping uses the following system of colors for the
syntax diagram:
- RED
- References to required fragments that have not been completed, or references to optional fragments that have been selected but not completed.
- WHITE
- Required keywords. You cannot select these, or tab to them.
- GREEN
- In general terms, indicates a reference to a completed fragment of the
syntax:
- Selected optional keywords (otherwise yellow)
- Required fragments whose subselections have been made to enable them to be resolved (otherwise red)
- Optional fragments whose subselections have been made to enable them to be resolved (otherwise yellow)
- YELLOW
- Optional keywords and fragments that are not currently selected (green when selected and complete; red when selected and incomplete).
