Composite physical options are specified over multiple lines, and contain one or more dependent options. If you add the composite option to the right pane of the Physical Options tab, all the dependant options are added with it. If you add a dependant option, the composite option is added as well to contain it.
Composite physical options are defined with the following syntax:
name [=] [%s|%d|%variable%] : composite=yes[, keywords]
{
sub-option
[sub-option...]
}
Everything entered before the colon is generated in scripts. The name is required by PowerDesigner, but you can place it between carets (<name>) if you need to exclude it from the final script. The %d or %s variables require a numeric or string value, and you can also use a PowerDesigner variable or GTL snippet.
The composite=yes keyword is required for composite options, and can be used in conjunction with any of the simple physical option keywords or any of the following:
|
