Editing Parameter

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

== Example Flowgraph ==

This flowgraph can be found at [https://github.com/gnuradio/gnuradio/blob/master/gr-fec/examples/fecapi_ldpc_encoders.grc]
