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. If you don't care about command line arguments, see the Variable Block.

The parameter value cannot depend on any variables.

Parameters

Label
Label that will show up. Leave blank to use the parameter id as the label.
Value
Value. Note, the parameter value cannot depend on any variables.
Type
When type is not None, this parameter also becomes a command line option of the form: -[short_id] --[id] [value]
The Short ID field may be left blank.
Show
To disable showing the parameter on the hierarchical block in GRC, use "Only in Properties" option
