Parameter parameter $value Label label string #if $label() then 'none' else 'part'# Value value 0 $type.type Type type enum $type.hide None type:raw hide:part Complex complex type:complex hide:none Float eng_float type:real hide:none Int int type:int hide:none Long long type:int hide:none String string type:string hide:none This block represents a parameter to the flow graph. \ A parameter can be used to pass command line arguments into a top block. \ Or, parameters can pass arguments into an instantiated hierarchical block. The paramater value cannot depend on any variables. Leave the label blank to use the parameter id as the label. \ The label only applies when this flow graph is instantiated as a hierarchical block. When type is not None, this parameter also becomes a command line option of the form --[id] [value].
