The following seems like a fundamental run-time requirement, but I find no discussion in any GR forum or documentation:
1. A GR block references parameter "frequency", which is set by command line switch --freq defined in a "parameter" block. 2. In the absence of command line input --freq, I wish to set the parameter from config file similar to the "variable config" block. Alternate approach: 1. A GR block references variable "frequency", which is set from config file via "variable config" block. 2. In the presence of command line input "--freq", I wish to override this variable. I cannot use a "variable config" as a parameter default, nor can I use a command line parameter as a "variable config" default. What am I missing? I use standard GR blocks, which I prefer not rewrite to handle config file input or multiple parameter/variable inputs. Thank you, -Mike
